Luckily history has shown that competitors still exist in a world where Microsoft tried hard to “extinguish”. macOS and Linux still exist, Chrome is the most popular browser (not IE), and most people who use Windows are fairly happy with it. You can try to point to Microsoft’s past behavior as proof that the future of GitHub is dystopic, but I don’t think their past behavior was particularly effective at snuffing out all competition and forcing people into their ecosystem. I suppose this is a matter of opinion, but I think being scared of GitHub sliding into terribleness does seem to be in the realm of paranoid conspiracy theories. Even if it does happen, git will always exist and there will always be alternatives.

I still buy a Windows license to play video games. I don't want to use Windows or buy a Windows license.
Of course, I could always choose to not play video games, so technically you're correct that I wasn't "forced" into their ecosystem. But I'm still there and I don't want to be. This is a direct result and present day residual benefit of their anticompetitive practices over twenty years ago. These are very long games that they play; you don't make hundreds of billions of dollars by accident.
Maybe that's true, but I'd like to think Windows is the current market leader because their desktop OS was the only one on the market at the time that was user-friendly and ran on any hardware (unlike OS X).
It seems that video game APIs require lots of investment, and Valve has worked on their version of Wine and other stuff which is quite successful at running Windows games on Linux, so you've got that option - giving your money to Valve through Steam. Or you can also get a console.
