Humanity needs steganography-as-a-service. But think how difficult it is to implement in a regime where all networks are monitored and even Android phones are assumed to be backdoored. Most services will re-encode data during transmission, potentially munging whatever secret happens to be embedded. And more generally, its the metadata that often de-anonymizes, not the data itself. If all the dissidents one day begin communicating via Lutheran Insult memes, its simply becomes a matter of picking one up and applying "rubber-hose" cryptanalysis to put an end to the party.
