To you. I’m perfectly happy to run a kernel level anticheay - I’m already running their code on my machine, and it can delete my files, upload them as encrypted game traffic, steal my crypto keys, screenshot my bank details and private photos all without running at a kernel level.

I disagree. I’m normally on the side of not doing that but increasing the player pool and giving players access to more people at the their own skill level is a good thing
