I’m indifferent, since I’ve got both installed, there’s no escaping having to use WhatsApp in many countries around the globe. If I want to keep in touch with family/friends then only one or two contacts use signal, for everyone else it’s WhatsApp or the alternative is SMS.
I’m also indifferent though because of I want the interoperability, Beeper is doing fine.
It’s certainly different, but for signal users who want to maintain that level of privacy, it’s probably something they want, right? From their perspective this is probably a good decision.
I’m indifferent because I’d personally rather have interoperability and Beeper gets the job done.
