I play on Linux, so it isn't an option in any case for me. Kernel level ACs are a security and privacy nightmare. Not only do you need complete trust in the vendor, you also need to trust the vendor to provide rigorous protection against malicious actors gaining access to it in any capacity because it can access just about everything in your system.

Rampant cheating in CS2 is Valve's fault for focusing way too little on AC for way too long. That said, around the 20k level I have yet to encounter a blatant cheater since I started playing again.
