In my experience with the social.coop TWG we already seem to have challenges sustaining attention to our Mastodon and Wiki. Not knowing more about why MeetCoop is deciding to shut it down, I can only assume that BBB is putting some support strain on MeetCoop? I think SocialCoop have gotten good use out of Jitsi through our May First membership, and while it is sad to see MeetCoop getting shut down, perhaps there are lessons there for perhaps not continuing to try to support BBB this way?
