From what I understand, the anti-cheat checks work, it's just that the permissions model on Linux is so much more coarse than on Windows that there isn't really a good way to tell the difference between a cheat and benign behavior. They end up with so many false positives that it's better to just not let the game run at all. Even something as simple as running "ps" on Linux looks through procfs and can show where in memory different things are loaded, probably getting flagged by the anti-cheat.
