I would like to also add this argument into the discussion, since I've seen a lot of people who are voting for federating with meta, with the argument that defederating just because we don't like someone goes against the idea of Fediverse, and interconnected network of diverse servers that is should inclusive and allows people to connect.
It's quite the contrary - allowing Meta in goes directly against the idea of Fediverse, and we should fight it as much as possible.
This is a literal quote from the main header on https://www.fediverse.to/
The fediverse is a collection of community-owned, ad-free, decentralised, and privacy-centric social networks.
Each fediverse instance is managed by a human admin. You can find fediverse instances dedicated to art, music, technology, culture, or politics.
Join the growing community and experience the web as it was meant to be.
Judging by this main selling point of the Fediverse, it sounds to me like Meta shouldn't be in the Fediverse do begin with, and every instance should defederate from them by default.
