Personally, I think anticheat should be optional. At lower ranks, cheaters and smurfs are often indistinguishable, but smurfing is commonplace and usually unpunished. I don't really care if I'm getting stomped by a sweaty tryhard on an alt account or by an aimbot, it sucks just the same. The solution is to move those players up the ranks until the cheaters and the tryhards are in the top ranks. Then you get the people who actually stand to truly benefit from cheat detection, and they tend to be the ones who would want anticheat even at the expense of privacy and system integrity so let them optionally enable it.

Us casuals at lower ranks should not NEED to run anticheat to play games at a casual level. It's a freaking game, nothing is at stake. I'm not competing in tournaments. I care more about my system being free of kernel rootkits than whether some guy who keeps headshotting me from a mile away is a real player or an aimbot. Matchmaking should be able to deal with the discrepancy regardless.
