I would use signal if I could convince people to use signal.

I could convince people to use Signal if all their conversations were on signal and they could talk to people on WhatsApp in a seamless way.

Right now you MUST have WhatsApp if you have any kind of social life. Signal is the other app that no one has because it’s kind of a pain in the ass to have two messaging apps.

I would love to switch to Signal, but inter-compatibility with WhatsApp is a must. The EU is essentially handing them a golden opportunity on a silver platter to become a mainstream app, and they are like nah, we good wtf
