I saw a while back that facebook is opening a twitter competitor which will use the ActivityPub protocol, and thus will be able to federate with other fediverse instances, I also saw they invited some fediverse instance admins for an "off the records" meeting in their HQ.

Question is, what is the general stance on this? Because I despise facebook with every fiber of my being, and would very much like to NOT have facebook lurk around these parts, as I understand there is an option to de-federate them like what happened with the exploading heads instance.
