It's worth highlighting how much organizing there's been here in the 18+ months since Meta first announced their plans to embrace, extend, and exploit the Fediverse.
@jat23's Closing the Door to Remain Open: The Politics of Openness and the Practices of Strategic Closure in the Fediverse is a great overview.
And from June 2023, the "Why the Anti-Meta Fedi Pact is good strategy for people who want the fediverse to be an alternative to surveillance capitalism" section of Should the Fediverse welcome its new surveillance-capitalism overlords? Opinions differ! talks about the importance of the #FediPact.
