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 too 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.
