I personally think this is an emotional overreaction and, based on the location of the recent incident (far from his plane), I think @ElonJet was not involved (and probably doesn't pose any threat to Elon), but I don't think that means his previous statements were a lie.

Anyone would change their mind and overreact after an attack on their child.

And in a broader context, the new policy seems like a good idea. In general, I suspect real-time location tracking does more harm than good, and none of us would tolerate a website tracking our location.
