In their defence: SMS is not secure enough for Signal standards
This was never the expectation. It provided a unified messaging interface and a shallow barrier to entry for people used to SMS.
I could install Signal on a phone for a neophyte user and they could use it as their normal SMS app. Then you could securely message them in the same interface and all of a sudden their messages between you would be secure.
Isn't that a vulnerability ? if a non-technical person has Signal as their main messaging program (including sms) aren't they at risk of not being able to tell when their messages are actually secure and when they aren't ?
I used it as well on my Android, and the UI made it pretty clear when you were sending 'unencrypted' texts to someone.
You're looking at it through the eyes of a competent user. It's obvious to us. It's not trivial to the general population. Just ask most iOS users what the difference is between green/blue bubbles - they have no idea other than "one sucks and means they use Android"
alright
