Samsung has released a new video in support of Google’s #GetTheMessage campaign which calls for Apple to adopt RCS or “Rich Communication Services,” the cross-platform protocol pitched as a successor to SMS that adopts many of the features found in modern messaging apps... like Apple’s own iMessage.

I always thought having SMS support in Signal created a significant risk of confusion about what kind of message the user was sending. Of course sophisticated users always knew the difference, but it's for software that emphasizes security it's better not to have to tell people who don't understand the technical details "it's secure unless...".

It's a valid point that it could potentially create some confusion when a user assumes that everything in Signal is secure. Unencrypted SMS threads could contain an open padlock icon and even an ominous red window border, but someone inevitably will not understand the difference.

However, my frustration has been how both convenience and security is reduced by removing SMS from Signal.

Many people will continue to use SMS for a variety of reasons, necessitating the use of an additional app. So now we have people continuing to communicate over this insecure protocol, but with the additional target vector of potential vulnerabilities in the supplemental app.
