Epic Games bought out rocket league and turned off a native linux build and faced no repercussions. Instead they made plenty of money.
That's the bar.
That said, devices like the SteamDeck run games on Linux (and that's without considering that every Android game ever is technically running on Linux too).
Let's face it though, PC gaming is already small enough these vs the consoles, that further splitting the marked isn't going to make sense for a lot of companies.
No. All the articles and testimony of game devs abandoning native Linux versions is from well before Proton was a thing, including Epic Games buying Rocket League and preventing you from playing the Native Linux build they had.
It also was not related to anti-cheat or underlying engine limitations or anything. Developers were clear that the problem was the massive lack of uptake mixed with a weirdly entitled community.
It's one thing to choose not to develop a new game for Linux. It's another to take a game that already runs on Linux and intentionally break it. You're guaranteed to alienate SOME people who are already fans of the game.
