I remember multiple times my chat switching to SMS when I did not have a stable data connection, though, admittedly, it’s been years since signal dropped support and I don’t remember the specific mechanics of the situation, but I specifically remember the same message chain would have both sms and signal messages in it.

I’ve used signal for at least 6 years now, and I remember online discourse being centered around why signal included SMS in the first place, with most of the discussion being around how people dislike the false sense of security comingling insecure data with secure data provided. The discourse didn’t change until after signal announced they were dropping support and suddenly people came out of the Woodwork talking about how horrible signal is for adopting good security practices.

Why doesn’t telegram or Whatsapp get the same treatment?
