Couldn't someone with WhatsApp/Facebook's resources find a way around the blockage? Write a bunch of different protocols and switch randomly - or use steganography - use machine learning to evade the block - buy a bunch of existing apps and hide the data in their protocols - put up a fake weak encryption, detect "dissident" talk, and in that case generate a long nonsense recording for the censors from the voices of the speakers, hiding the true message steganographically :-) - or basically anything they can come up with. Or - Saudi Arabia is not such a big market - make a complete theatric fuss about it and complain about human rights and so on, close all FB and WhatsApp connections and burn all bridges, and milk it for publicity. (Only being half serious here :-) but I would be really tempted to do something mischievous in their case rather than comply.)
