I didn't know that! I used to be a member of FidoNet (pre-internet network that provided e-mail and usenet-like services) back in 1990s and any commercial activity and encryption was similarly prohibited - relay operators were even supposed to read their users' mail and delete any messages that violated the rules. I don't think there's any chance of this coming to the internet though. There are just too much uses for encryption besides conspiring for terrorist attacks.
