Think your company is locked into Microsoft's world of Windows, Word, and Teams? You're not alone, and the UK's top competition cop is starting to think that might be a problem. On Tuesday, the Competition and Markets Authority (CMA) announced it's launching a major investigation into Microsoft Corporation's (MSFT) sprawling business software empire.
This isn't just about whether you can get a better deal on Excel. The regulator says we're at a "pivotal moment" as artificial intelligence gets woven into the productivity tools hundreds of thousands of UK businesses and public sector bodies use every day. With new AI assistants like Copilot gaining traction, the CMA wants to make sure the playing field is level before Microsoft's dominance becomes even more entrenched.
The formal probe, called a "strategic market status" (SMS) investigation, is a big deal. If Microsoft gets that designation, it gives the CMA more power to step in and fix things it thinks are broken. The main concern? That Microsoft's software licensing rules might be making it too hard for other cloud companies to compete, locking customers into the Microsoft universe.
Cloud Giants Make Concessions
But here's the interesting part: the investigation announcement came with some immediate wins for customers. After some arm-twisting from the regulator, both Microsoft and Amazon.com, Inc. (AMZN) have outlined steps to make their clouds play nicer with others. They've promised to lower those pesky "egress fees"—the charges you pay to move your data out of their cloud—and improve interoperability for UK customers. The goal is to make it cheaper and easier for a company to use multiple cloud providers instead of being stuck with one.
The CMA says it will be watching closely to make sure these promises turn into real savings and flexibility. It also hinted that more might need to be done to help companies switch providers or adopt a multi-cloud strategy. We'll get an update on their progress in about six months.
This action follows a cloud market investigation last year where the CMA found that Amazon and Microsoft hold significant market power. Barriers like high egress fees and technical hurdles that make it hard to mix and match services were limiting choice for customers.
