No one is intentionally making it possible to cheat in their games. Cheaters and cheat detection/prevention are in a constant arms race. You can't just allow a little cheating. The people that develop cheats will share them and those cheats become more widespread.

Your whole argument is also based on the idea that there is no such thing as bad publicity. This is incorrect. If your game gets a reputation for being full of cheaters then people will leave your game and probably not come back. If the first time you hear about a game, all you hear is that it is full of cheaters are you going to head out to the store to buy a copy?

How is it different than today? The game is slightly cheatable (scripters exist) and they are counterating it and getting some publicity out of it.

Being so good at anti-cheat that there is nothing to talk about seems like something so far away it's not worth thinking about.

But that said, I doubt the gains from allow "controversy" around cheating would outweigh the benefit of not having any cheating in the game. Not having cheaters is it's own talking point. Withing the competitive gaming community, cheating is already a major talking point and having little to no cheating is already a major selling feature.
