I think you a misunderstand why people cheat. There is nothing "nowadays" about playing unfair. Minecraft is also a bad example, as it's also cheated, and botted to hell. If there is anything to gain in any context, and you get enough people interested, the people will try to maximize that gain, and some will not care about the rules, or the intent of the context.

I do agree about the conclusion though. The solution for the disappointment in online matchmaking is singleplayer, and multiplayer with friends. Both completely eliminate the bad actors.
