"eyes on going public"
Well, there's the death knell. Not that it was awesome to begin with, just a stepping stone to get people away from WhatsApp.
Come on Signal, SimpleX, XMPP!
I struggle to understand why XMPP isn't the de facto messaging standard around the world, I was using it on my first Android phone in 2009, 15 years ago - and was able to seamlessly message people on computers even then. Granted it was hell on battery back then.
