Is Elon not a vanguard/blackrock man? Like apple/msft/google(via alphabet) are companies steered/managed by their ppl (and amazon once JB sells his shares)?
For instance he is "like" msft CEO, which is also starbucks CEO, both companies steered and managed by vanguard/blackrock ppl (that include very probably the CEO as biggest share holders weight a lot on CEO choice then on the whole hierachy of management).
It is the same for "alphabet"(google)/apple and many other companies in big tech.
You missed the point: Elon Musk is spacex and telsa, if spacex and telsa "are" vanguard/blackrock, then Elon Musk is one of their CEOs, even though he bought twitter on its "own" "money".

SpaceX is also privately held. Vanguard has nothing to do with it, neither do I think BlackRock. With Tesla, they are holders, but largely through index funds. And Elon has control.
There is a public market index hypothesis, but it pointedly doesn’t apply to Elon or his companies.
Apple wouldn't want to remove twitter because then people will start using the web again (the web app is ~ identical). But probably nothing is happening here, just noise.
