It seems the combativeness of Twitter has increased with it becoming more hivemindy, not the other way around. The people leaving twitter are generally less combative than those staying / joining, so I imagine it will devolve further into a pit of rabid fighting dogs.

Similarly, I expect Trump and Elon will have a falling out rather quickly. Two megalomaniacal narcissists don't generally play nicely for very long. When that happens, Elon won't be able to help himself from whacking the bees nest he's created, by criticizing Trump. I expect the combativeness of twitter to skyrocket soon afterwards.
