good points. yeah, client side anticheats are still vulnerable and I think they're mostly just popular out of pure laziness. Making a good server side anticheat takes a lot of thought into what is and isn't possible so it's easier for a company to just slap on some slop and get 80% of the way there.

in valorant's case, their anticheat is also a great date collection software to beam every possible identifier straight to John Data or whoever it ends up with.
