I would bet that every single person commenting here thinks of him- or herself as being deeply invested in privacy, ranting against things like ad tracking, etc. But as soon as someone (or some ones) you don't like, or have no affinity with, wants to have the same privacy afforded to every single person who drives a car, all bets are off.
Or are you suggesting that people (including the police!) should be allowed to have real time, constant information about where you drive to every day?
Just because it's a plane, and just because it's a rich person, doesn't make it any less of a privacy violation.
