I can't speak to SpaceX shareholders because they are private, but of the public Tesla that's also associated with Musk, there are shareholders who want him out because his public behaviour is interfering with the business interests, and that argument will gain weight as a result of stuff like this.

Is that "deserved" depends a great deal about how you model the entire world, but activists investors are a thing and they do fight company management.

The only time they tried to do tracking on where these posts and sockpuppets were coming from, they ended up in Israel (this is a common practice, I'm assuming to make tracing and legal action more difficult. In Portugal the bots come from Angola).

Its clear that the same disinformation farms that are running in the US were duplicated to Brazil, by the same people (Bob Mercer / Steve Bannon). Proof of that was of course, the deeply personal relationship between Bannon and the Bolsonaro family (when he was out of jail he would visit all the time), and the faux January 6th that was replicated in Brazil after Bolsonaro's defeat.

You have to understand that the population of Brazil has A LOT less education than the population in the US or Europe. They are far more malleable to disinformation.

One of the worse examples I can think of is the disinformation campaign that was activated after the murder of Marielle Franco, who was tagged in fake photos with local Rio drug dealers - while she was still dead inside her car. So a few minutes after the murder, you had a giant disinformation campaign launched. Since it was so fast, the only reasonable conclusion is the murderers control a disinformation bot/sockpuppet farm.
