Because when tyranny is present... You don't get rid of it by asking nicely. That's kind of the whole point of the "tyrant" part of the word. You need people willing to go against the tyrant (terrorists, by strict definition, since the tyrant would make it illegal to go against the tyrant), and you need a lot of them (so "mob"). And they need to be organized (so, "rule").

Terroristic mob chaos won't get change. Terroristic lone wolfs with rules won't get change. Peaceful mob rule won't be given power. Peaceful lone wolfs definitely won't be given power.

Every dictator, oppressor, or authoritarian tyrant is taken down by the masses acting against the dictator in an at least semi-organized fashion. Tried and true through history. Why do you think they'd change it up, just for funsies?
