The dumbest part of the article is that the author seems to be blaming Valve for games that chose a kernel level anticheat that only works with Windows and consoles.

But because many anti-cheat apps still aren’t compatible with Linux (hence, SteamOS), installing Windows on Steam hardware is currently the only way that gamers can enjoy titles that require them.

That isn’t even a Windows issue. That is a publisher choosing an anticheat that has stupid limitations.
