The history of Signal has been to provide the security properties we're talking about without users having to think about it or understand. To suddenly remove forward secrecy is a very big change, and it isn't one that they seem to have acknowledged or documented. Like this blog post: they are making an announcement that they have a "post-quantum ratchet," when they have effectively removed the ratchet. It's theater.

I think you missed the point entirely. You can't have security without thinking about it. You can have vague sense of security, which is the theater you are talking about.

Show me a company anywhere that can provide security without user thought and deliberate action. It's a fantasy to believe anything you don't have to think about isn't theater. Hell, if you aren't thinking about it, you're one of the actors in that theater.
