Psyonix stated that they would offer refunds for Linux/ macOS users. In the first few days post announcement, everyones' refund was being denied. It appears that this has since been resolved. I received my refund yesterday.
They do push for making more games easily playable on Linux, but they aren't pushing the game developers to release for it.
Are you able to Google "non violent communication".
You know that I'm german and think I"m not smart, or what?
Or is this a misinterpretation?
Epic does nothing like that and even actively pushes games to be exclusive this Windows only, using their Windows only client.
Don't Epic make Unreal Engine, which supports Linux? I'm not sure it's fair to say they do nothing, if that's the case.
There are quite a few games that work great with proton, but can't be played online because the anti-cheat won't run. Like Arma3. It runs great in linux, but the binaries are always 3-6 months behind the windows ones. so your choice is to find a server with 2-3 people on it, or run it on proton, see lots of servers with hundreds of people, and can't connect.
Also the problem with fortnight, pubg, etc.
So yeah, the store works - but that doesn't mean the "Linux games" work, or work fully, with network.
If the latter, I agree but no storefront actually meets that standard right now. Valve happily sells stuff on Steam that barely works on Windows and before the new refund policies they'd perma-ban your account if you tried to refund a broken game.
