I still cannot comprehend their logic for why having full SMS integration would be such a disaster. It just makes no sense and I wish they’d admit that it isn’t a security concern but is just that they don’t want to do it. They just don’t want to, and don’t care that this policy makes it harder for users to adopt and use their service.

I know that SMS is a US-specific thing. But at least in the US, most people regularly interact with SMS. Having a platform that supports SMS means you can basically live in that platform – this is a major part of the success of iMessage.

The idea that it would create huge security gaps… I just don’t believe. I think the kind of user who wants to be on Signal clearly understands that SMS is not secure. All they need to do is have a clear visual indication when you are texting instead of using Signal, which isn’t that complex.

Instead, people like me who might try using it as their primary platform just see no point. None of my friends use it. So why should I even have it installed? And none of my friends see a reason to install it because I and everyone else don’t have it installed. If I could use it as my SMS app I might have it installed and lived-in, which greatly lowers that barrier.
