If you think there aren't hackers on console, you're deluded.
> Your server side logic can't detect wall hacks, ESPs etc.
Correct, neither do the invasive tools. You can get these things without modifying memory or the game, which is the majority of what the kernel level stuff keeps on eye on.

True, there is no answer here. Again, if the provider is this sophisticated, then EAC isn't helping here. Then it is just the usual cat and mouse, and the kernel level is moot.
> But applications should be able to attest the environment is not modified, which is what desktop Linux lacks. Windows, macOS and Android do have methods to do this.
Also true, but they are frequently circumvented anyway, so ultimately you're at the same level of Linux from a functional standpoint.
I know you're probably thinking that we should just hit all vectors, and I agree to an extent. The problem is that those who charge for cheats easily circumvent (yes, easily, they are literally within 24hrs sometimes of adjusting to modifications by anti-cheat software) the methods you're claiming help. While the data you get from users on the server end doesn't paint a whole picture, it is the source of truth of what the game decided happened, so it becomes the only thing you can rely on. I know folks who specialize in this area who basically believe that online competitive shooters are basically lost and it isn't worth the investment to fight it.
I am of the opinion we should just go back to dedicated servers and have self moderation. Sure, you get false positives if the owner or their mods suck at the game, but at least the players can do something about it. CS2 is a fucking nightmare at the moment.
