No one really tries to break encryption, when side channel attacks can capture a message during the process of encryption.

No one thinks in encrypted text. The plain text is always created and then translated over to the enciphered copy. The plain text will always exist in some way, so that a message may be proof-read before sending. Even if printed on the sceen of a secure display monitor.

If an environment is stifling enough, it might be painfully obvious that someone is stepping out of line to work on carefully disclosing secrets. Obviously laws don’t matter in China, and if there’s a scent of dishonesty in the wrong context, I’m sure it wouldn’t take much find a way to watch every second of someone’s humble existence, if they’re not above executing pregnant women to send a message about what not watching your husband gets you.
