Yeah, I imagine Linux support would be more like a supported Linux distro rather than generic Linux support. Something like SteamOS but with kernel anti-cheat and secure boot from the start.

Big question is whether they can make craching the anti-cheat it hard/unpredictable enough that the publishers will trust it. If the publishers release such a platform and someone releases a live distro that can crack it with 3 mouse clicks, that's a lot of wasted effort.

I have no idea how effective the Windows anti-cheat is, but I imagine that Linux tooling in general is going to make it harder to lock a user out of controlling their own machine.
