Just because we don’t usually see backlash it doesn’t mean it’s a good thing. The average player puts up with absolutely rigged games which treat paying for advantages as fairness.
Personally I only see cheating as a problem if it affects people who haven’t agreed to it, but the solution is not preventing all modification. Games are better off for modding and customization. They could cut off modified games from having matchmaking or any input on a global game mode while still allowing players to run their own servers however they want.
