It's fully FOSS and un googled notification system

I didn't know about Molly
Session also started out as a fork of Signal, but then they realized that the architecture wasn't very decentralization-friendly, so they changed their messaging system to use Tor, and now I think they have their own decentralized network.
Every normie that I've managed to bring over to Signal uses the Signal app, but my daughter and I have been on Molly for about 2 years now. Love it.
Me too. Molly for the win!
