There are ways to do that job that don't involve poking the proverbial dragon every waking minute. You can call Elon a hypocrite for banning people who attack him relentlessly, but all humans are hypocrites. Perhaps they should take a break from the "Elon beat", because their reporting appears increasingly personal in nature.
The crowd that got banned seems unusually thick-headed, and they'll probably just attack Elon (and Twitter itself) even harder once they get unbanned. Karl Popper explained it better than I can, but Twitter doesn't have to extend unlimited tolerance to those who seek to destroy Twitter.
