I want to echo a previous comment of mine on this topic:

With the rise of mainstream-compatible, as in a standard gamer can get them running and use them with a similar frustration level as Win11, Linux first systems like steam deck, steam machine and even steam frame, there is a real, even if currently low, pressure for big publisher to support Linux/SteamOS. I somewhat hope/fear there will be a blessed SteamOS version that supports anticheats enough for publishers like EA, Epic and Riot to accept the risk.
