I wouldn't really say they use that power to "snuff innovation," Windows was the operating system which is why everything is built around it most of the time and they worked on making sure XCloud would work with the Steam Deck. It's just how it works with any operating system being different in that you'll need to jump through additional hoops to make something from other operating systems work with other ones. Not saying Windows isn't flawed or that Microsoft doesn't have its own corrupt practices, but I wouldn't say that they attack compatibility for non-Windows things.
