It'll be interesting to see if the people who've been lauding musk for his supposedly pro free speech attitudes will reckon with what's been happening in actuality, or if they'll just accept this as "freedom for me but not for thee".
Hopefully this makes more people aware of just how much power social media companies have, and have always had, over the public discourse and that results in the institution of legal and/or technical measures that limit that power across the board. I'm not optimistic though, given how much of the public attention right now seems to be focused on admonishing Elon personally rather than on the overall system that makes this kind of censorship possible.
Anyone that actually wanted to use this data to harm Musk would have no trouble simply using the exact same original data.
Anecdotally, I did see the @ElonJet account, and have still never seen the source of the data.
Wow, you have to reach back 25 years, and it's an absolutely terrible example because it has nothing to do with a constant publication of location to the general public. Instead paparazzi used their own private communications (paparazzi who saw her board in Sardinia told other paparazzi in France). And her death wasn't caused by someone who found out her location and wanted to do her harm.
"Safety claim by Elon" is also completely meaningless since he's literally the person who wanted this shut down.
So two really bad examples over 25 years is not evidence for your claim.
Finally, using public information to say the state or country Elon has recently flown to is a far cry from actually giving away his current location.
