Ok, so people in the government realised, that there exist encryption methods, which can not be "decrypted", and technology makes encryption accessible to everyone.

When will they realise, that there is no way to detect, whether a message is encrypted or not-encrypted, and there may be multiple levels of "tunneling". It is not possible to find out the original form or the source (app) of information.

Monitoring online communication is in not any simpler, than monitoring verbal communication between every 2 people.
