Boy, what a complicated and serious question. We should form a committee to discuss exactly where our community places reasonable boundaries and adjudicate blurry edge cases. Who could have predicted that a policy like "if it's legal, it's allowed" would lead to problems? Surely no one with a few dozen billion dollars to set on fire would be that unbelievably stupid.

Some people did indeed abuse that knowledge, but it was rare.
A few people were, by request, "ex-directory" and not listed, but again, that was rare.
Most people were not only absolutely fine with their phone number being public info, it was more useful then than a publicly-known email address is now.
You are likely correct! However, I don't think that anyone here believes the @elonjet account was doing either, besides possibly you.
Also, "and you know it" is insulting and rude, and I don't agree with it or appreciate it.
When he's not the object of the speech in question, he seems to think that things like calling people pedophiles is free speech, so he generally seems to be a free speech maximalist and I'm guessing the answer might be yes.
I don't consider a lot of things to be free speech that musk apparently does, but there's a big difference between him being a free speech maximalist in general and just supporting free speech when it's convenient.
Consider the following: The Twitter files contains a lot of private information and outs employees whom have received direct harassment.
The ElonJet account contains publicly available information on a very accessible site. This does not make a statement about Musk nor does it tell who is inside the jet at the time.
Which is closer to doxxing?
He published what they said and the reason for doing it publicly is to ensure the current administration and administrative state (which would be the people at the heart of his accusations) would also have motive to bury the information. I'd also guess that such disclosures also help distance him from any legal action.
Though the fact that you immediately jumped to the government conspiracy angle it seems like you've planted your feet and aren't going to move. It's not doxxing because it's someone you agree with.
