To be particular, "bans on e2e" are specifically targeting encryption between individuals on communications platforms.
They won't and can't ban secure comms between a user and a site during a web session. But they want the messaging platforms to be able to reveal the plaintext of conversations to law enforcement.
Of course "they" can't stop coded messages, or me sending encrypted messages via email or media platforms. They're just making it harder for non technical people (some of whom are criminals) to have privacy.
