I did not read that to mean that Linux is at fault, I usually would use "X's faults" colloquially to mean drawbacks, not literally, X is at fault and therefore responsibility for this.
Ah well then we have a slightly different interpretation. I would read "the faults of <x>" as "the flaws of <x>", which would then imply a flaw of Linux is why aggressive anticheat doesn't work when it is just companies deciding it isn't worth their time.
