Microsoft Corp. is facing a class action lawsuit in the UK, with claims amounting to over £1 billion ($1.3 billion), alleging that the company overcharged for licensing fees related to its Windows Server software used in cloud computing. The lawsuit claims that Microsoft has been charging inflated license fees to businesses using cloud services from competitors like Amazon Web Services (AWS), Google Cloud, and Alibaba. The legal action, filed at the Competition Appeal Tribunal, suggests that Microsoft's licensing practices are anti-competitive, potentially forcing businesses to use its Azure cloud services. The claimants argue that these practices have led to higher costs for UK businesses, stifling competition in the cloud computing market. Microsoft has not yet publicly responded to the lawsuit.
