Don't forget the work that Steam has done for Linux gaming. They're funding the development of DXVK and some other projects. And they've brought in Proton, which enables Windows games to be run on Linux in one click just like any other game on Steam. You can use your cloud saves to start playing a game on Windows. Pick up right where you left off on Linux. And then go back to Windows if you want. They've even undertaken support for getting these games under Linux so the actually developers don't have to do anything.
Meanwhile Epic Games' CEO mocks Linux on social media.
And the introduction of Rockstar's launcher broke a game that was working under Linux.
