I’m sympathetic to the perspective, but actually no, someone less wealthy couldn’t be similarly tracked. To be tracked in this specific way, you must have exclusive ownership of plane(s) with tail numbers.
If you fly commercial and don’t publish your itenirary publicly, then the public won’t know your association with the flight. If you charter a private flight, then again no one knows that chartered plane == you. You have to actually own a dedicated private plane for anyone to use these resources to confidently track you in particular.
So I’m broadly sympathetic to the plight of celebrities with respect to paparazzi and stalkers and such. But with the availability of charter flights, hard for me to be too sympathetic of someone afflicted by private plane tracking.
