Here’s how WhatsApp plans to interoperate with other messaging apps

This is a most excellent place for technology news and articles.
My understanding is that many chat applications incliding whattsapp use the signal protocal. However sadly signal nolonger wants to federate with anyone which i think is a huge shame and really could be the next step in global encrypted communications.
IIRC it wasn't the signal protocol, just the encryption methods that were shared with WhatsApp. I don't think federation was ever on the cards.
Where did you see that Signal won't federate with anything? Can't find info on it anywhere.
Wikepedia, and some devs of some of the devs for alternative clients where complaining about it.
Edit: Deleted because I mixed up two different products lol.
I still think they could make federation an opt-in preference though.
