You only try to control something if it becomes a nuisance to other people.
This is how our law works in real life. You don't go and poke your nose in other people's private life. That being said, auto clicking bosses doesn't pose a nuisance to other people. However, autoclicking arena does, you can luck your way to grab other people's arena chests. Even worse, some top people can use their bot to grab people's chests everytime they had a new one (the top 5 especially).
Quest, bosses -->private in a sense they don't affect other people. Arena --> public as they involve player interaction. And you say the arena hardly impacts one's progress?
