I don't really want to start a debate on the Signal SMS dropout but ...

They could have put a big red warning and a disclaimer you have to read once for the unsecured SMS. It would have been fine.

Yes, you would have to maintain that but I think it would definitely have been worth it considering how much reach they lost dropping this feature.

I stopped using Signal when they did, and that's one less tech user advertising their secure app.

It's a shame because I think this will slowly kill the project.
