That is entirely baseless. I'm fairly certain that whole affair was just some social media assistant offering money to someone for Musk to have slightly increased privacy and PR(since private jet use is really bad for the environment). They offered like $5k to take itf down which to Musk is literally like giving a homeless person a couple quarters. All flight traffic is public though. Banning a Twitter account would do nothing as all that information is already public record. You can track whoever you want on sites like Flightradar. I really doubt Musk cares that much at all, if he was ever actually even aware that the Twitter account existed.
