sounds like you need to go talk to the FAA since they are the ones originally publishing this info rather then a twitter account that is just consuming the info.
Companies that use the data published by the FAA are required to not display information about planes that are part of the LADD program (which Elon's Jet is).
This data is not from the FAA, but from ADSBExchange, which crowdsources the data.
It’s funny how even despite the fact I didn’t address this situation here to try to speak generally people inevitably found there way back to Musk - but the entire point of doxxing is you take public information and repackage it and focus it in a way to help target an individual. Just because the FAA publishes flight information doesn’t imply they are doxxing someone, if someone built a custom app to track everything a specific famous person was doing including this FAA data, that would be closer to what doxxing actually is.
