EVIL – At the stinking end you have the #dotcons with full on technicology and privacy nightmare. Facebook messenger, whatsapp (facebook) and telegram (who lies) imessage (just trust us)
NEUTRAL – At the next stage you have the ethical, good technologically working, socially problem apps like signal (king who dose not federate) and matrix (a non-industrial #NGO standard)
GOOD – Then you have the usable, but complex good tech like modern jabber/XMPP that ticks the boxes but still suffers from the #geekproblem
Then you have the #geekproblem with IRC and blockchain spam.
Or for a less “moral” view on the same subject, a post from the #openweb
You could have a chat compass. Centralized/decentralized on one axis, Open/Closed on the other.
Centralized/Closed: WhatsApp, Telegram
Centralized/Open: Signal, Jitsi, BBB, RocketChat (maybe)
Decentralized/Closed: Pre-Microsoft Skype
Decentralized/Open: Matrix, XMPP, SSB
