Why is republishing this information unethical and immoral? (Your words)

It is doxxing as his plane's location is a proxy for his location, similar to his cellphone.

Also, it violates Twitter's rules about physical location sharing

Not really. There is no guarantee that Elon is on the plane. He could loan it to a friend or one of his companies VPs. The plane could be at it's home airport, fly to another airport to pick Elon up, fly to a third airport to drop him off then return to the home airport. Elon would have been on only one of the three legs.

Retract this statement, now that this crowdsourced data was used to stalk Elon's family.

KTHX

Uh..why? There is nothing false about it...

This whole article is about private information. The flight data is, as enough people already told you, not private information. For good reason.

Social Security Numbers used to be treated as quasi public data too.

He's not doing anything unethical or immoral.

invasion of privacy ?

What's in the plane is private, where the plane is isn't.

Twitter (and Musk) has access to pinpoint each of their users with the same precision, I feel it's a poetic balance.

whose, the airplane's?

This is all public information already. There is no invasion of privacy.

He is merging in public data and private surveilliance data from personnel at airports, and then publicizing it.

It is stalking.
