Mentioned before... strange that news hasn't reported any people figured out how to commandeer, repurpose, reprogram, and even deorbit some of these birds. Seems likely many of the older models are using obfuscation rather than strong crypto. Now with RC drones people can overfly uplinks to grab samples, sensitive GnuRadio SDR could capture scatter and bounce from birds, tropo, moon, etc. Lots of old satcom dishes laying around. Guerrilla radiopunks need to be playing with short and long range comms methods... tropo, ELF, baloon and other airborne relays, solar power mountaintop rigs, etc... and encryption.
