> What business is it of yours that I might write my own?

If they're providing online servers for you to play on with other people, under the condition that you aren't cheating and they are responsible for stopping cheating for everyone, they very much do care and it is their business, if you want to use their servers.

Having custom drivers is how you get wallhacks or custom mouse control macros that eliminates some of the challenges imposed by the game (e.g. automatic recoil control).

For a single player game, I agree, who cares, but for online games that live and die by competitive play and stopping cheaters so people can enjoy it, there's only so many options of how to find cheaters and so much resources to put towards it, so you get stuff like this.
