On October 28, 2025, the digital landscape was abuzz with the unveiling of Microsoft’s AI-powered assistant, Copilot, showcased across devices in Mulhouse, France. However, beneath this innovative development lies a potential storm brewing for the tech giant. The UK Competition and Markets Authority (CMA) has initiated an investigation into Microsoft, focusing on allegations of misleading marketing practices associated with its Microsoft 365 subscription plans.
The crux of the issue revolves around the subscription changes made to Microsoft 365 Personal and Family plans, particularly the introduction of Copilot as a new feature. Initially, Microsoft offered Copilot at no additional cost to subscribers, creating a perception of added value. However, as customers approached the renewal phase of their subscriptions, many found themselves transitioned to a higher-priced plan that included Copilot, unless they proactively opted for a different plan or canceled altogether. This shift raised eyebrows, especially given that new subscriptions for Personal and Family plans were no longer available without Copilot.
For context, the annual cost of Microsoft 365 plans with Copilot comes in at £25 ($33.2) more than the old “Classic” versions, which retained the original features at the same price. This significant jump in cost has prompted the CMA to scrutinize whether customers were adequately informed about the various plans and their corresponding price differences prior to making renewal decisions. Hayley Fletcher, senior director for consumer protection at the CMA, emphasized the importance of transparency, particularly in the current economic climate where household budgets are under strain. “At a time when household budgets are squeezed, it’s important that people are clear on the price and subscription plans available,” she stated.
The investigation marks a pivotal moment under the CMA’s enhanced consumer enforcement powers, which, since April 2025, allow the regulator to determine breaches of consumer laws without the need for court proceedings. This newfound authority has already yielded tangible results, with the CMA securing refunds totaling over £1.95 million ($2.5 million) and imposing fines nearing £6.2 million ($8.2 million). Companies found in violation of consumer laws face hefty penalties, potentially reaching 10% of their global turnover.
This scrutiny of Microsoft’s practices is not confined to the UK. Australia’s competition regulator has also launched legal proceedings against the company, alleging that customers were misled following the introduction of Copilot. In a bid to mend relations, Microsoft issued an apology to Australian subscribers in November 2025, acknowledging that it “could have been clearer” regarding the availability of lower-priced plans without AI features and offering refunds to affected customers who opted for the Classic versions.
Italy’s competition authority is similarly probing Microsoft for its subscription renewal practices, questioning whether the company’s actions constituted aggressive commercial behavior and whether sufficient information was provided to customers during the renewal process.
As the investigation unfolds, it raises critical questions about the ethical responsibilities of tech companies in communicating changes to subscription services, particularly as AI tools like Copilot become increasingly integrated into everyday applications. The implications of these cases extend beyond Microsoft, challenging industry standards for transparency and consumer trust in a rapidly evolving digital marketplace.
In an age where AI is set to redefine our interaction with technology, the outcomes of these investigations could herald significant changes in how companies approach consumer communication and pricing strategies. As Fletcher aptly noted, “When a business changes its subscription plans, customers need clear and timely information about their options.” The resolution of this matter could serve as a benchmark for future practices, ensuring that consumers remain informed and empowered in their choices, even amidst the complexities of modern technology.
