Epic games goes out of their way to be hostile to Linux users. I'm at the point where I just ignore windows only games. And I'm the exact type of person they'd want to convert cause I tell all my friends about my gaming experiences. They could even take proton and use it in their store.
This is basically my opinion as well. There are enough games that run on Linux that I don't have time to play them all, so if the game is windows only I skip it.
The steam chat app is kind of terrible and there was a Linux UI bug that caused UI lag a few years ago. Epic Games just can't replicate the goodwill.
