Flightradar24, as well as all sorts of similar services (FlightAware, ADSB-Exchange, etc.) let anyone watch the location of any aircraft with ADS-B in real time (as well as list everywhere the plain has been and playback previous flights)

Not true. "Any aircraft" is only valid for ADSB-Exchange. All others filter.

There’s no filtering on non-commercial aggregators like PlanePlotter either.
