I thought we already had Matrix
Matrix is decentralized but its not federating in a way like activity pub is doing
ActivityPub isn’t the only way to federate.
It’s federating the same way email does. Anyone can spin up their own server. And if they want anyone can spin up their own software.
No that’s decentralization, federating is when you can share the info natively outside the platform.

share the info natively outside the platform.

I’m not even sure that makes sense.
Federating is based on protocols not platforms. And what does it mean to share natively if not using the protocol?
