- Public figures, like politicians, top businessmen, and so on don't get the same amount of privacy and protection as regular Joe. You can follow them and track them. If you have power and influence, you don't enjoy the same privacy protections as others. That's a really good principle to have.
- Elon Musk himself is know for punching down that violates this principle. His M.O is to point his crazy followers against regular Joes and then playing innocent. "It was not me".
For my money, there's absolutely nothing wrong with twitter disallowing "person trackers". Legality aside, whether it's Elon Musk or Nancy Pelosi, the subtext of these trackers is creepy and threatening and banning them from some platform is fine.
They were defending Twitter's biased nontransparent censorship before only because it aligned with their bias. Now that it doesn't match their bias, they see the problem.
Finally, welcome to the club!
