Stating the obvious but corporate files are public and so are flight data. This is not doxxing; it's not even particularly advanced OSINV. It's also not sharing "exact location in real-time". It's federal (FAA) law. [See images for quick workflow on finding corporate jets, Musk as an ex.]

I feel like some of this is a Streisand effect. None of these methods are new. You can literally even tune into live Air Traffic Control comms.

One could always elect to avoid flying by private jet, though!
