UK Opens Formal Probe Into Microsoft Copilot 365 Price Hikes as Three Countries Investigate in Parallel

The UK Competition and Markets Authority launched a formal investigation on July 28 into whether Microsoft misled Microsoft 365 Personal and Family customers by auto-rolling renewals into higher-priced Copilot-included plans while making a cheaper AI-free tier effectively invisible. Australia and Italy are running parallel probes in the first major regulatory test of AI feature bundling in subscription software.

UK Opens Formal Probe Into Microsoft Copilot 365 Price Hikes as Three Countries Investigate in Parallel The UK Competition and Markets Authority launched a formal investigation on July 28 into whether Microsoft misled Microsoft 365 Personal and Family customers by auto-rolling renewals into higher-priced Copilot-included plans while making a cheaper AI-free tier effectively invisible. Australia and Italy are running parallel probes. The case is the first major regulatory test of AI feature bundling in subscription software. If the CMA finds against Microsoft, it could require explicit opt-in for AI features that increase cost, a ruling that would affect Adobe, Google, and every other subscription company bundling AI into existing tiers. The Catalyst The UK Competition and Markets Authority launched a formal investigation on July 28 into whether Microsoft misled personal and family customers of Microsoft 365 about their subscription options. The core complaint: Microsoft added Copilot /compare/github-copilot-vs-cursor to existing subscription tiers at no extra cost, then auto-rolled renewing customers into higher-priced plans that bundle the AI assistant whether they wanted it or not. Australia and Italy are running parallel probes. Microsoft said it's reviewing the CMA's claims. How We Got Here The sequence of events is straightforward and infuriating in equal measure: - <<<BOLD Late 2025:<<<BOLDEND Microsoft begins adding Copilot features to Microsoft 365 Personal and Family subscriptions. Copilot appears in Word, Excel, Outlook, and PowerPoint as a sidebar AI assistant. No additional charge — it's framed as a free upgrade. - <<<BOLD Early 2026:<<<BOLDEND Microsoft announces restructured subscription tiers. The old "Microsoft 365 Personal" at $69.99/year is phased out. In its place: Microsoft 365 Personal at $99.99/year with Copilot included. A new "Microsoft 365 Personal Classic" at $69.99/year exists but is hidden behind multiple menu layers and requires customers to actively opt down. - <<<BOLD Renewal cycle:<<<BOLDEND Subscribers who let their annual plans auto-renew are migrated to the $99.99 tier by default. The cheaper tier exists but is effectively invisible — no notification, no explicit choice, and no opt-in to the higher price. The CMA's investigation centers on whether this constitutes an unfair commercial practice under the Consumer Protection from Unfair Trading Regulations 2008. The key legal question is whether Microsoft made "the real choice" — the cheaper tier — sufficiently available to consumers. The Broader Pattern This isn't an isolated case. It's a template that every subscription software company is watching closely: - <<<BOLD Adobe<<<BOLDEND has experimented with bundling Firefly AI into Creative Cloud tiers without opt-out - <<<BOLD Google<<<BOLDEND added Gemini /glossary/gemini to Google Workspace Business plans, raising per-seat pricing by roughly 30% for the base tier - <<<BOLD Zoom<<<BOLDEND introduced AI Companion as a free add-on, then restructured pricing tiers to require the higher plan for continued access - <<<BOLD GitHub<<<BOLDEND added Copilot to Team and Enterprise plans by default, raising seat prices The playbook is identical: add an AI feature for free, wait for adoption to create dependency, then restructure pricing around the AI feature. Users who don't want the AI feature cannot downgrade without losing functionality they previously had in their base subscription. Why This Matters The Microsoft 365 probe is the first major regulatory test of AI feature bundling. If the CMA finds against Microsoft, it could force subscription companies to: - Offer AI-free tiers at the same price as pre-AI subscriptions - Require explicit opt-in for AI features that increase subscription cost - Disclose pricing changes more clearly before auto-renewal - Maintain legacy pricing tiers for existing customers The parallel probes in Australia and Italy suggest coordinated regulatory interest. The European Commission is also monitoring the situation, though no formal investigation has been opened. What Microsoft Says Microsoft's official statement: "We are reviewing the CMA's claims and will cooperate fully with the investigation. Microsoft 365 subscriptions continue to offer a range of options to meet customer needs, and we believe our pricing and subscription practices are clear and fair." The market's reaction has been muted — Microsoft stock is down 0.8% since the CMA announcement — but regulatory risk for AI bundling is building. If the UK, Australia, and Italy all reach similar conclusions, other markets will follow. The Bottom Line Microsoft took a calculated risk by auto-upgrading millions of subscribers to a more expensive AI-included tier and making the cheaper option hard to find. Three countries' regulators want to know if that crosses the line from clever retention strategy to unfair practice. The answer will determine how every subscription company approaches AI feature pricing for the next several years. Related Articles Get AI news in your inbox Daily digest of what matters in AI.
