Have you ever wondered why the user/kernel split in modern operating systems even exist in the first place? And no, it’s not to annoy the heck out of game developers. Kernel programming requires much more care and effort than userspace programming, and if you grant kernel access to any application that asks for it, you're bound to make the whole system unstable, insecure, and underperformant. Operating system developers spend a lot of time designing interfaces that are safe to use, and applications should strictly stick to those. Taking a “move fast and wreak havoc on the whole system” approach with your customer’s devices is not acceptable however justified you think you are.

This is all assuming that the developers of anti-cheating software have any sense of self-restraint and strictly limit themselves to anti-cheating, which is obviously not the case given their track record. The reality is much, much worse and no amount of legal gibberish they stick in front of their users before installation would make it any better.
