They are tracking his private jet movement. His kids could get kidnapped....Nobody checks on those things. You put them in SM and anyone has access to them. If Elon was ok with that information to be out he wouldn't have banned it from Twitter. If Elon thought that the information couldn't be harmful to him or his family he would have allowed it.

Why can't you respect a father for doing his job?
Now Will you're a father, if you thought that any information on SM could have 1% chance to put your son and wife in a harmful situation would you allow it?

Now I know you are trying to defend your technology and want to outsmart me by putting words such as "public flight information" in the sentence to make it seem OK. Making information like this easy to access for anybody is different from it existing.
