Microsoft Teams
Microsoft Teams is a workplace collaboration platform combining chat, video meetings, file storage, and app integration, with over 320 million daily active users. The platform was found by EU regulators to have been illegally bundled with Office 365 to crush competitors like Slack, resulting in binding unbundling commitments through 2032.

Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Teams launched as a free add-on to Office 365, offering solid collaboration features with no additional cost. While the bundling strategy gave Teams an inherent distribution advantage over Slack, the product was still new and lacked the deep ecosystem integration that would later create lock-in. Microsoft's competitive conduct was notable but not yet subject to regulatory action.
Microsoft began auto-installing Teams with Office 365 ProPlus updates, force-installing the app for millions of enterprise users. Dutch GDPR investigations uncovered massive telemetry collection across Office products. Teams was announced as the replacement for Skype for Business, consolidating enterprise communication under a single product and deepening ecosystem dependencies.
Following pandemic-driven growth to 270+ million users, Microsoft implemented its first M365 price increase in a decade and introduced Teams Premium as a paid add-on gating AI features. Slack's EU antitrust complaint was formally under investigation. Microsoft began massive layoffs while simultaneously announcing $60 billion in share buybacks, establishing the pattern of shareholder extraction alongside workforce reductions.
The EU opened a formal antitrust investigation and Microsoft preemptively unbundled Teams in Europe. Microsoft retired the original Teams Free plan without data migration, pushing small businesses toward paid tiers. Ten thousand employees were laid off as Microsoft pivoted to AI. The forced migration to the new Teams 2.0 client began, drawing widespread complaints about degraded user experience.
Microsoft settled the EU antitrust case with binding commitments but immediately rebundled Teams at higher prices while eliminating enterprise volume discounts. The ACCC sued over deceptive Copilot pricing, the FTC expanded its broad investigation, and the UK CMA recommended Strategic Market Status designation. Over 15,000 employees were laid off in 2025 alone despite record profits, while $42 billion was returned to shareholders.
Alternatives
Project management and team communication with a flat per-company pricing model ($299/month for unlimited users) that avoids the per-seat extraction of Teams' pricing. Simpler than Teams, focused on async communication and project tracking. Hard switch if your organization is deep in Microsoft 365 — Basecamp doesn't replace Outlook or SharePoint. Scores 13, the lowest enshittification of any workplace tool in the database.
The direct Teams competitor that filed the EU antitrust complaint, and the reason Microsoft bundled Teams in the first place. Slack is purpose-built for workplace chat, with better search, integrations, and a less bloated interface. Hard switch — Slack doesn't replace Teams' video meetings natively (you'd use Zoom or Google Meet), and your SharePoint and OneDrive integrations don't transfer. Scores 43 vs. Teams' 58.

Microsoft OOXML format entrenches Office lock-in despite open format commitments
Microsoft introduced its Office Open XML (OOXML) format as the default in Office 2007, positioning it as an open standard while embedding proprietary extensions and undocumented features that degraded fidelity when opened in competing applications. The ISO standardization process was controversial, with allegations of committee-stuffing in national standards bodies. Competing office suites like OpenOffice and later LibreOffice struggled to parse OOXML files correctly due to undocumented rendering behaviors, making migration away from Microsoft Office impractical for organizations with large document libraries.
Microsoft announces Teams as Slack competitor
Microsoft unveiled Teams at an event in New York City, positioning it as a direct competitor to Slack. The decision to build Teams rather than acquire Slack was reportedly opposed by Bill Gates, who advocated for enhancing Skype for Business instead. Slack responded with a full-page 'Dear Microsoft' ad in the New York Times.
Microsoft Teams launches worldwide
Teams launched globally as part of Office 365, offering chat, video meetings, file storage, and app integration. The product was initially led by corporate vice president Brian MacDonald and was available to all Office 365 commercial customers at no additional cost, leveraging Microsoft's massive installed base.
Microsoft cuts thousands of sales jobs in cloud restructuring
Microsoft laid off thousands of sales employees, less than 10% of its sales force, as part of a major reorganization to pivot toward cloud services. About 75% of cuts were outside the U.S. The restructuring refocused sales teams on Azure, Office 365, and cloud infrastructure, representing an early signal of Microsoft's willingness to cut roles to realign toward higher-margin subscription and cloud businesses.
Microsoft releases free version of Teams
Microsoft launched a free tier of Teams offering unlimited chat, 10 GB team file storage, and integrated Office Online apps, targeting small and midsize businesses. The free version was capped at 300 users and available in 40 languages worldwide. This expanded Teams' reach beyond the Office 365 enterprise customer base.
Dutch GDPR investigation finds Office telemetry violations
A Data Protection Impact Assessment commissioned by the Dutch Ministry of Justice found Microsoft Office violated eight GDPR regulations through covert data collection. The investigation revealed 23,000 to 25,000 different event types transmitted to Microsoft from Office applications, including email subject lines and document content. Microsoft had not properly informed users or provided opt-out mechanisms.
Teams auto-installed with Office 365 ProPlus updates
Starting July 2019, existing Office 365 ProPlus installations began receiving Microsoft Teams automatically as part of standard updates. Teams also auto-started on login. Administrators could opt out through Group Policy or registry keys, but the default behavior force-installed Teams for millions of enterprise users without explicit consent, cementing its distribution advantage over competitors.
Microsoft announces Skype for Business retirement
Microsoft announced that Skype for Business Online would be retired on July 31, 2021, giving customers two years advance notice to migrate to Teams. This consolidated Microsoft's enterprise communication products under Teams, eliminating internal competition and further deepening ecosystem lock-in by making Teams the sole supported platform.
EU data watchdog raises 'serious concerns' over Microsoft contracts
The European Data Protection Supervisor published findings expressing 'serious concerns' over the compliance of EU institutions' Microsoft contracts with data protection rules. The investigation found incompliant data processing agreements, lack of control over sub-processors, no audit rights, and insufficient safeguards for data leaving the EEA. Microsoft later updated its Online Services Terms in response.
Teams usage surges 894% in first week of COVID lockdowns
Microsoft Teams usage increased 894% in the first week of U.S. remote work during the COVID-19 pandemic. Daily active users leapt from 20 million in November 2019 to 44 million by late March 2020 and 75 million by April. Virtual meeting minutes increased 1,000% in March alone. The surge cemented Teams as critical enterprise infrastructure.
Slack files EU antitrust complaint against Microsoft
Slack filed a formal antitrust complaint with the European Commission alleging Microsoft illegally tied Teams to Office 365, force-installed it for millions of users, blocked its removal, and hid true costs. Slack alleged Microsoft abused its market dominance to 'extinguish competition' in breach of EU law. The complaint drew parallels to Microsoft's 2009 Internet Explorer bundling case.
DOL settles with Microsoft over contractor hiring discrimination
The U.S. Department of Labor's Office of Federal Contract Compliance Programs reached a settlement with Microsoft over allegations of hiring discrimination at multiple facilities. Microsoft agreed to pay $3 million in back pay and interest to affected applicants. The settlement highlighted governance challenges in Microsoft's massive contractor workforce, which had long faced criticism for creating a two-tier labor system where contract workers performed similar functions to full-time employees but received fewer benefits and protections.
Teams reaches 115 million daily active users
Microsoft announced Teams had reached 115 million daily active users and introduced a new 'daily collaboration minutes' metric, reporting over 30 billion collaboration minutes in a single day. The explosive pandemic-driven growth locked organizations deeper into the Microsoft ecosystem, with 80% of enterprises reportedly calling Teams critical to business operations.
Skype for Business Online retired, Teams becomes sole platform
Microsoft retired Skype for Business Online, forcing all enterprise users to Teams as the only supported communication platform. Users on Skype for Business were automatically migrated to Teams-only mode. The retirement eliminated the last internal alternative for organizations already in the Microsoft 365 ecosystem, deepening switching costs.
Microsoft announces first M365 price increase in a decade
Microsoft announced the first substantive pricing update since launching Office 365, with increases of $1-$4 per user per month across most tiers, effective March 2022. Office 365 E1 rose from $8 to $10 (25%), E3 from $20 to $23 (15%), and Business Premium from $20 to $22 (10%). Microsoft justified the increases by citing 25 new apps and 1,400+ new features added over the previous decade.
Microsoft announces first $60 billion buyback program
Microsoft's board approved a $60 billion share repurchase program, the company's largest-ever buyback at the time, along with an 11% dividend increase to $0.62 per share quarterly. The company had accumulated $130 billion in cash. The buyback signaled prioritization of shareholder returns alongside continued expansion, establishing a pattern that would intensify alongside later workforce reductions.
EDPS launches coordinated investigation into M365 telemetry
The European Data Protection Supervisor announced an ongoing investigation into EU institutions' use of Microsoft 365, as part of the European Data Protection Board's 2022 Coordinated Enforcement Action. The investigation examined whether the European Commission's use of M365 products including Teams complied with data protection regulations, particularly regarding telemetry collection, data transfers outside the EU/EEA, and sub-processor oversight.
Microsoft introduces Teams Premium paywall tier
Microsoft announced Teams Premium at $10/user/month, gating AI-powered features including intelligent meeting recap, auto-generated chapters, and custom branded meetings behind an additional paywall. Some features previously available in standard Teams licenses were moved behind the Premium paywall within 30 days of the service's February 2023 general availability launch.
Microsoft lays off 10,000 employees amid AI pivot
Microsoft announced 10,000 layoffs, approximately 5% of its workforce, while simultaneously investing billions in OpenAI and AI infrastructure. The cuts hit HoloLens, engineering divisions, and Halo developer 343 Industries hardest. The layoffs came amid Microsoft's ongoing $69 billion Activision Blizzard acquisition and were framed as preparation for AI-driven growth.
Microsoft restricts third-party access to Teams data via EWS
Microsoft fully restricted third-party application access to Teams message data through Exchange Web Services, effective January 31, 2023. The change forced all third-party integrations to use Microsoft's Graph Teams Export API, which has more restrictive licensing requirements and rate limits. This deepened ecosystem lock-in by narrowing the data access pathways available to competitors and migration tools.
Microsoft retires Teams Free Classic, disrupts small business users
Microsoft retired the original Teams Free for small businesses, introduced in 2018, in favor of a new 'Teams (Free)' plan with reduced features. Legacy data was not carried over and no direct migration path was provided. Features removed included Location Sharing, Safe secure storage, mini Teams, Google Calendar sync, and Tasks. Users were pushed toward paid tiers.
CWA and Microsoft finalize labor neutrality agreement
Following the closure of the Activision Blizzard acquisition, Microsoft affirmed its commitment to the CWA labor neutrality agreement covering nearly 10,000 workers. The agreement prevents Microsoft from opposing union organizing efforts and provides streamlined paths to collective bargaining. Activision user research workers became the first video game user researchers to unionize under the agreement.
EU Commission opens formal Teams antitrust investigation
The European Commission opened a formal investigation into Microsoft's bundling of Teams with Office 365 and Microsoft 365 suites, three years after Slack's complaint. Germany-based alfaview joined as a second complainant. The Commission expressed preliminary concerns that Microsoft was leveraging its dominant position in productivity software to restrict competition in communication tools.
Microsoft unbundles Teams from Office 365 in Europe
Under regulatory pressure, Microsoft began offering Office 365 and Microsoft 365 suites without Teams in the European Economic Area and Switzerland. A standalone Teams product was offered separately. New subscribers in the EEA could no longer purchase bundled suites with Teams. However, existing customers could continue using their bundled plans, limiting the competitive impact.
Microsoft cuts 1,900 gaming jobs post-Activision acquisition
Microsoft laid off approximately 1,900 employees across its gaming division, roughly 9% of the unit, three months after completing the $69 billion Activision Blizzard acquisition. Cuts hit Activision Blizzard, Xbox, and Bethesda studios. Critics noted the layoffs contradicted labor commitments made during the acquisition approval process.
Mozilla report documents Microsoft dark patterns in browser choice
Mozilla published 'Over the Edge,' a detailed research report by Harry Brignull and Cennydd Bowles documenting Microsoft's dark patterns for pushing Edge over competing browsers. Findings included Teams and Outlook links force-opening in Edge regardless of default browser settings, user-agent sniffing to block Firefox from Teams, and Windows updates resetting default browser choices.
Forced migration to new Teams client begins
Microsoft began automatically migrating classic Teams users to the new Teams 2.0 client built on WebView2. Two-thirds of users had refused to switch voluntarily. Users reported degraded search, chaotic notifications, broken file editing workflows, and inability to revert. Microsoft extended the deadline to July 2024 after pushback from large enterprise customers, but the classic client was eventually retired entirely.
Teams unbundled globally with standalone pricing
Microsoft began selling Teams separately from Office 365 and Microsoft 365 worldwide, following the EU-only unbundling in October 2023. Teams Enterprise was priced at $5.25/user/month as a standalone add-on. Forrester analyst described the move as 'just a sneaky price hike,' noting the unbundled suite plus Teams add-on cost approximately 30% more than the previous bundled price.
EU issues Statement of Objections over Teams bundling
The European Commission sent Microsoft formal charges via a Statement of Objections, finding preliminary evidence that Microsoft had abused its dominant position since April 2019 by tying Teams to Office 365 and Microsoft 365 suites. The Commission found interoperability limitations with rival products reinforced Teams' distribution advantage. Microsoft faced potential fines of up to 10% of global revenue, approximately $21 billion.
Critical Copilot Studio vulnerability exposes internal data
Security researchers at Tenable disclosed CVE-2024-38206, a critical SSRF vulnerability in Microsoft Copilot Studio with a CVSS score of 8.5. The flaw allowed authenticated attackers to bypass protections and access Microsoft's internal infrastructure, including the Instance Metadata Service and internal Cosmos DB instances. The vulnerability raised concerns about AI data processing security across Teams and the broader Microsoft 365 ecosystem.
Microsoft announces $60 billion buyback alongside layoffs
Microsoft's board approved a new $60 billion share buyback program and a 10% quarterly dividend increase to $0.83 per share, matching its largest-ever repurchase authorization.

FTC opens broad antitrust investigation into Microsoft
The U.S. Federal Trade Commission launched a comprehensive antitrust investigation into Microsoft, examining cloud computing, software licensing, and AI practices. It was reportedly the most significant federal probe of Microsoft since the 1990s DOJ case. The FTC issued civil investigative demands forcing Microsoft to turn over internal documents, and later escalated by subpoenaing six or more competitors for evidence.
Teams Phone price increased 25%, monthly billing premium added
Microsoft increased Teams Phone Standard pricing from $8 to $10/user/month (25% increase) and Frontline Workers from $4 to $5. A new 5% monthly billing premium was imposed on customers choosing monthly over annual payment, penalizing flexibility. These increases were layered on top of the separate Teams standalone charges introduced the previous year.
Microsoft lays off 6,000 employees amid record profits
Microsoft cut approximately 6,000 employees, 3% of its 228,000-person workforce, targeting engineering, product management, and LinkedIn staff. The layoffs came despite an 18% year-over-year net income increase and were widely interpreted as AI-related restructuring. A University of Washington professor called the cuts historically unprecedented for a company of Microsoft's profitability.
Microsoft cuts 9,000 more jobs, largest since 2023
Microsoft announced approximately 9,000 additional layoffs, its largest workforce reduction since the 10,000 cuts in January 2023. Combined with the May 2025 round, Microsoft eliminated over 15,000 positions in 2025 while posting record quarterly revenue. CEO Nadella said the layoffs had been 'weighing heavily' on him. Microsoft simultaneously invested $80 billion in AI infrastructure.
UK CMA finds cloud competition 'not working well'
The UK Competition and Markets Authority concluded its cloud services market investigation, finding that competition is 'not working well' and that Microsoft and AWS hold 'significant unilateral market power' with roughly 30-40% market share each. The CMA recommended Strategic Market Status investigations for both companies, with powers to impose targeted interventions on pricing transparency and interoperability.
Zulip exposes Teams data export tool as potential vaporware
Zulip published an investigation revealing that Microsoft's Teams data export tool may be 'vaporware.' One organization spent 36 days, 21 calls, and 29 email conversations across five Microsoft support teams attempting to get a sample export, ultimately receiving only an error page. The export tool was limited to tenants of 500 users or fewer, with Microsoft acknowledged to be 'effectively lying' about data portability.
EU accepts Microsoft Teams unbundling settlement
The European Commission accepted legally binding commitments from Microsoft to resolve the Teams antitrust case, avoiding potential fines of up to 10% of global revenue (~$24 billion). Core unbundling commitments are binding for seven years; interoperability and data portability obligations extend ten years. Microsoft agreed to offer suites without Teams at reduced prices and committed to competitor interoperability.
ACCC sues Microsoft for misleading 2.7 million Australians
The Australian Competition and Consumer Commission sued Microsoft for allegedly misleading 2.7 million customers about Microsoft 365 subscription options. The ACCC alleged Microsoft told subscribers they must accept Copilot integration and price hikes (45% for Personal, 29% for Family plans) or cancel, while hiding a third 'Classic' option accessible only through the cancellation flow.
Teams rebundled with higher prices, volume discounts eliminated
Microsoft rebundled Teams with Office 365 and Microsoft 365 suites for new enterprise customers, just two months after the EU settlement. Simultaneously, Microsoft eliminated Enterprise Agreement volume discount tiers (Levels B, C, D), removing automatic 6-12% discounts for large organizations. Analysts noted the unbundling-rebundling cycle effectively resulted in higher net pricing for most customers.
CEO Nadella admits Copilot integrations 'don't really work'
In an internal email reviewed by The Information, Microsoft CEO Satya Nadella told engineers that Copilot integrations with Gmail and Outlook 'for the most part don't really work' and are 'not smart.' Despite charging $30/user/month for Copilot, adoption was faltering. Nadella assumed an unusually hands-on role in fixing the product, effectively becoming the company's top product manager for the struggling AI assistant.
