Right, which should be different for each vehicle/flight and if it is
used for control of that particular vehicle/flight, is pretty moot now...

Having said that, if there was sensitive content in those transmissions
that was in addition to real-time control of the vehicle, there would be
a significant interest in preventing others from acquiring it.  This
seems like a weakness of the system.
