Meta — previously Facebook — has banned a number of accounts that keep tabs on private jets belonging to the world's rich and powerful, including Mark Zuckerberg, Elon Musk, and Donald Trump.
Non-military flight paths collected by the FAA are considered public record, meaning there is no difference between checking on a grandparent's flight path and checking on Musk's in the eyes of the law. However, Meta is not the government, and has acted on its right to stomp out the information.
