Some see it as their duty to fight back against unjust laws/rules. You and I might do it by breaking terms of service, Musk does it by purchasing the platform and adjusting the terms. Two sides of the same coin really, only difference being which end the agency is coming from.
That's like agreeing to take your shoes off when entering a building, leaving your shoes on, and then complaining when the employees/owner/whatever asks you to leave if you're not going to take them off. If you think a rule is stupid, then rebel against it by not agreeing to it
