Earlier quoted context omitted.
Do you mean the presence of anti-cheat software makes them anti-player? Because I’d disagree. It’s a lot of work and expense to combat cheats, but is very much appreciated by many players (when it works)
Or they could just not trust the clients, instead of throwing the problem over the wall. A lot of these games with fancy anti cheat protection the cheat tools basically just tell the server "spawn me a vehicle right here" and the server just does it. Garbage.
Btw tell me exactly how an aimbot that takes the visuals from the player's screen and tilts the player's cursor so (or not so) slightly towards identified moving targets, are to be avoided from the server. Modern cheating is already a hard-ass problem to solve, much more so if no client-level monitoring is desired.
