The pact is a declaration of intent to block any Meta-governed instances that try to federate. There are some useful stats here about which, and how many instances have already committed to the pact. All types of Fediverse instances have signed, including some Lemmy instances, though it seems to be especially Mastodon instances that have signed it.

Is this something you have an opinion on, or already made a decision about, @jerry@infosec.pub? Is it something we should discuss as a community?
