From the opinion piece:
Last year, I pointed out how many big publishers came crawlin’ back to Steam after trying their own things: EA, Activision, Microsoft. This year, for the first time ever, two Blizzard games released on Steam: Overwatch and Diablo 4.
The problem is that the complaints aren’t “It might be a good product, I can’t try it because they don’t support my OS of choice and that’s understandable considering the small user base” which is perfectly reasonable, the complaints are “Epic sucks because they don’t support Linux and [insert a bunch of stuff that hasn’t been true for years or that also applies to Valve as a company]” which isn’t reasonable.
It’s not just that though. A lot of people have already pointed out that Epic appears to be actively hostile towards Linux by removing compatibility for games that had it before. People have also pointed out that turning on Linux compatibility for EAC is fairly trivial, but they refuse to do it. For some games, Linux users have to go through extra loops just to make it work. So when it looks like a company is treating a certain demographic as something that’s worth less than shit for no apparent reason, I’m not surprised that they’ll have a negative attitude towards that company.
And say what you want about Valve, but they have pushed Linux compatibility and it’s not surprising why Linux users have a more positive view of them over Epic. As I’ve already said, your argument reinforces this point.
