I think Musk has been the single most important individual in transforming electric vehicles from a niche product for dweebs into a mainstream commercially viable enterprise that will largely replace internal combustion vehicles within our lifetimes. That's a very significant achievement regardless of whether you like his politics or his Twitter feed.
As for Twitter, I can only marvel at how quickly the line went from "It's a private business, they can do what they want, they have no obligation to you, go start your own platform if you don't like their terms of service!" to "This is the Marketplace Of Ideas, it's a vital platform for public discourse, it's too important to be controlled by a narcissistic oligarch!"
