What are they? After looking at their web page, it looks like they run a Mastodon server, and:

CoSocial, officially CoSocial Community Cooperative, is a member-owned organization with the purpose of providing democratically-run open social media.

We […] launched a Lemmy instance (which was later sunset)

Why was it sunset?

I wonder if they pay fees to BC Coop?
