Think of #Musk as a bored troll.
He likes to get a rise out of people because at least it's something interesting to watch, so his moves at #Twitter are proving highly effective.
He's toying with people, and they're giving him exactly the sorts of responses that he wants to elicit.
It's probably not healthy for him, and it's definitely not healthy for the society that descends into the negativity, but as with all trolls, the way to handle them is not to feed them (as the old internet adage went).
He basically says, If you're going to give me these buttons to push, I'm going to push them.
We should stop giving him the buttons, but obviously we won't.
