> So your claim is that it's actually impossible to implement "efficient" anticheat on Linux? That's interesting.

This is absolutely not my claim and it's a pretty absurd interpretation of what I wrote.

My claim is that there's ample evidence that anti-cheat on Linux happens to be a pretty hard technical blocker and multiple companies at this point have chosen to ban the platform outright and take a revenue loss over trying to overcome this blocker. This directly contradicts your claim of "obviously few or no hard technical blockers" existing.

This does not imply it's impossible to implement. It implies that at this point implementing it would not justify the cost. This pretty much 100% matches the any reasonable interpretation of the term "technical blocker"

You seem to be fixated on picking apart the wording of my original comment, so let me help you understand it:

> There are obviously few or no hard technical blockers preventing Valve and the Linux community from supporting any game that runs on Windows

'Few' there is doing a fair amount of work: it allows that some significant (or "hard" if you prefer) blockers may still exist (this is consistent with my own observations of game compatibility in aggregate). So your (implicit) insistence that I claimed there are no blockers is obviously nonsensical already. But, furthermore, I went on to say this:

> unless it's been specifically engineered to block Linux

Which precisely describes a game that previously worked on Linux, with anticheat even, but now has been updated to remove that compatibility! It also describes a game whose anticheat has been configured that way since launch.

Also, your implication that "hard technical blocker" and "not worth it to implement" are interchangeable is ridiculous in any scope, whether you're Valve deciding whether to commit tens or hundreds of man-years to Proton development or a one man shop considering a hacky workaround in a client's dated web framework.

You are just barking at the mailman. I'm done here unless you can respond to the actual substance and nuance of my comments rather than a strawman.
