The primary motivation of crypto experts is to make a plausible encryption that only they, but not their opponents, can read. The primary employer of crypto experts is the secret police, who want to bypass encryption.
Backdoored crap is a billion dollar industry. Lots of companies competing to be 'plausible' and yet 'backdoored' at the same time.
In every electronic conversation, imagine a secret-policeman in a hi-viz jacket looking to 'make-his-name' and 'advance-his-career' at your expense. And be careful with your words.
