What I would love to see is open source kernel level anti-cheat.
The issue of course is that would reveal just how much of our data those things Hoover up.

That being said, I agree it would be harder to maintain an open source anticheat effectively.
The client can lie about being modified. E.g. it can send false hashes.
How much data a in-kernel or user-land anti-cheat can easily be detected by observing the traffic that flows out from your network, so it really doesn't matter if it's open source or not.
The biggest roadblock to a open source in-kernel anti-cheat is not "exposing the amount of data they extract from you", but rather it exposes how the anti-cheat is working, which is working against the efficiency of the anti-cheat. If you know how they detect you're cheating, it's much easier to overcome that hurdle.
In most cases, security-by-obscurity is obviously flawed, but when it comes to cheat/fraud detection, exposing how it happens makes it's core value less efficient.
