Future of linux gaming

I use Linux as my primary operating system. However, I recently watched a video from 'The Linux Experiment' channel that explained many of these games aren’t actually Linux games; they are Windows games running through a compatibility layer. This means we are still at the mercy of Microsoft. If Microsoft decides to introduce custom APIs that are only accessible through Windows, it could break everything, effectively ending Linux gaming. Microsoft could easily implement such changes, and game studios would likely follow that because of Windows' dominant market share. What's your take on this? Do you think we're headed for a bright future?
