  We can expect that message metadata will be ( or, is) captured and analyzed by governments to identify specific targets for further ... action. Taking that as a given, we can expect motivated parties to build their own comms networks to protect message metadata. It's possible now in dense urban catchment areas, with advances in wireless tech (and the coming price decline in launching your own satellite) wider area private comms becomes more possible. Pretty soon only the dispossessed  will be easily mass surveilled; just another brick in the divide.
