Copilot Bundling: An AI Upgrade That Looks Like a Stealth Price Rise
The current regulatory investigation into Microsoft Copilot pricing and subscription bundling is about whether an AI upgrade was used to push customers into more expensive Microsoft 365 plans without clear, informed consent, testing the limits of transparency and fairness in the subscription economy. In January 2025, Microsoft added new features, including Copilot, to its consumer Microsoft 365 package and then raised renewal prices for the tier containing those tools. At renewal, users were automatically moved to the pricier Copilot tier unless they switched plans or cancelled their subscriptions entirely, creating a default upgrade path that benefits the company more than the customer. From a user-rights perspective, the core issue is not that Copilot costs money, but that avoiding it required extra effort and attention most people never realised they needed to spend.
Where Transparency Broke Down: Defaults, Disclosure and the £25 Question
Microsoft did offer a cheaper “Classic” plan without Copilot, yet remaining on the Copilot-equipped version cost £25 more per year. That price difference is significant enough that the way it was communicated matters. The competition watchdog has said its investigation will examine whether customers were given “key information about the plans and the difference in cost to understand the options available to them before making a decision.” The design choice to auto-renew people onto the more expensive tier flips the usual logic of consumer choice: rather than actively opting in to AI features, users had to notice, interpret, and then opt out. When ordinary customers discover after the fact that they could have avoided an annual increase, it starts to look less like innovation and more like a quiet tax on inattention.
Regulators Push Back on Forced AI Adoption
The competition authority is not attacking AI itself; it has said it is “strongly supportive of AI adoption and the benefits this could bring to real people's lives” but insists that “no one should be treated unfairly.” The probe focuses on how Copilot AI features were bundled into Microsoft 365 apps such as Word, Excel and Outlook and then used to justify higher subscription costs. This is not an isolated flare-up. A parliamentary committee previously questioned Microsoft about the price increases and the need to opt out of the more expensive Copilot plan, while regulators in another jurisdiction extracted an apology for failing to communicate the cheaper Classic option clearly. Together, these challenges show a growing regulatory intolerance for “forced upgrades”, where AI is pitched as added value but functionally tied to paying more, whether users want the technology or not.
The Real Stakes: Subscription Bundling and Consumer Trust
This CMA antitrust probe is ultimately a test of whether AI momentum can coexist with basic consumer protection standards. Microsoft says “consumer trust and transparency are priorities” and that it will work constructively with the regulator, but the product and pricing choices tell a more complicated story. Bundling Copilot into a core productivity suite and shifting the default to a higher-priced tier looks less like customer-centric design and more like revenue optimisation disguised as progress. If regulators conclude that customers were misled or inadequately informed, it will send a warning to every AI vendor: innovation cannot depend on foggy pricing pages and hidden opt-outs. The lesson should be simple—AI features need to be clearly priced, clearly optional, and clearly explained. Anything else is not transformation; it is upselling by stealth.
