If I understand the grand-parent correctly, his/her point is that the lack of privacy gives more control to the inheritors as they can use that as a way to pass more stringent laws governning communications and enforce blanked surveillance as a way to quash dissent. There is an assymetry because the procecutions under these laws will not be as effective against of those who have the means to defend themselves against them (basically money and influence). Also the loss of encryption will probably not affect all means of communication but getting mass-appeal apps like FB and WhatsApp to forego with encryption means most people would then easily become 'surveillable'.
