and, as evidenced by Grand Theft Auto and Counter-Strike, players continue playing with hackers.
There is even reason for (say, for example) Rockstar to leave hackers alone in GTA : they act as artificial whales to lure real players into buying in-game currency in order to keep up/seek revenge.
There are a few games I can think of off the top of my head that have a symbiotic relationship with hackers.
