> Are they supposed to 'keep' people esp non-techies from using RCS 'by default' and make them use SMS? The app that cares so deeply about encrypted communication?
While I agree with most of what you said, it appears you are implying that RCS provides a security guarantee somehow that Signal is impeding. RCS is badly fragmented, mostly not E2E (except Google private E2E extension), and does not have Apple's buy in. Signal does clearly indicate that SMS chats are not secure.
Signal originated as ChatSecure- the encrypted SMS app.
