This kind of thinking is exactly what's killing signal. Why would you want to gatekeep the security of others instead of making t as accessible as possible?
To me this feels like signal not understanding that their intended userbase and their actual userbase are very different, as I can't imagine the number of people that use signal solely for it's e2ee is comparable to the number of people that use it as their sms app.
Well, isn't the point that more people using signal strengthens the privacy/security of everyone? I would be sad if I wanted to send a message to gerty, and I find out he stopped using signal because of this.
It's not like I wouldn't still want to message him, right?
Convenience is extremely powerful in getting the layman to adopt this kind of tech, and I feel like it should be prioritized.
