You seem to be blaming linux users for vendors' lack of interest in launching the software you want for the linux platform. It's not their fault. Nobody really expects Adobe or Epic to launch their products just on linux, but in today's age when a game gets shipped to multiple platforms and Photoshop has OSX and Windows versions, what's one more platform to add to the build matrix? Granted linux is not exactly a single uniform platform, the market is small, and the users are the most vocal about submitting issues. However Valve proved it can be done, and other vendors are just hiding their laziness with "market share" excuses. And to your last point, to my knowledge nobody is really up in arms against Valve because "closed source" because if you want to support a open source OS you inadvertently contribute to the ecosystem one way or another, and their work with Proton and flatpak and Steam OS is more than worth it. Edit: I guess I should have read TFA before replying to you, but as a linux user of almost 20 years I disagree with some of the fringe opinions in it, as you can tell from what I wrote. :D
