Let's be honest – Musk doesn't know what the hell he is doing here.
Regardless of whether or not you agree with his actions these days, it does at least seem a significant departure from how the public perceived his actions in the past. Over the past few years his actions have steadily grown more.. loud, at the very least.
.. It's.. interesting.
His growing group of admirers started treating his like a messiah, and he fully embraced that role, along with the behaviors that it engenders upon someone. He's not special in that way. It's a position a lot of ambitious people would like to be in.
Tesla, SpaceX, Boring Co have ambitious objectives with clear right/wrong answers. You put something in orbit or don't. Your car goes 500km with 70kWh of energy or it doesn't etc. You can inspire smart engineers to work hard to meet ambitious goals that require creative thinking.
Twitter has none of that, it is more like a club. Having the loudest speakers or brightest lights isn't going to make your club the best club. There is a certain baseline of technical competence required, yes, but mostly its about attracting the right crowd (being extra nice to some people, kicking others out) and making sure everybody has a good time. Musk might have actually succeeded with this using his previous person, but his new culture warrior schtick isn't gonna work.
Technically, he was never CEO “at Paypal”. He was forced out as CEO of X.com the second time just before it took the name of the main product (which it had acquired with the company that developed it, with Elon returning as CEO with the acquisition) and became PayPal.
You'll also have to ignore that he's built companies that land rockets back on Earth and produce millions of EVs. He's objectively demonstrated ability.
It continues to look as if Musk believes a Twitter turn-around is largely a technical project--rather than tending to a community of users.
