For a pure singleplayer game no one absolutely interested about how do you play a game includes cheating exploiting moding etc.
But in this game there are possible multiplayer aspects which are advertised and calucated into the games price.
If someone buys a game and found out in the multiplayer part everything is an abusefest then the buyer can be disapointed with the product cuz for his/her playstyle the x part of the game which he/she paid as well is totaly unuseable for him or her.
Well we could argue about this on and on. I am just pointing about leave abusable things in this game can lead to unsatisfied custumers which is bad for the company.
An at this point you have no ask yourself which buyer layer do you want to satisfy more, the "casual" or the "hardcore".
