I wonder if private communications were ever private in history.
Mails were opened with vapor and resealed, the FBI has been tapping phones since Bell invented the phone, people would listen to private conversations through the wall… etc…
With public access to modern cryptography I think it is the first time in history that we reached a level of being untamperable (especially with OTR messaging) and soon with the SafeNetwork it won’t even be possible to detect who is who and from where.
