But you weren’t discussing Twitter you were discussing Bluesky. They built it with decentralised identities so that users owned their identities and can move about freely. You saying people could “easily” move to another instance isn’t reality. People already find the Fediverse too difficult, as you and I discussed under a different thread people actually care about their data which also includes their posting history. Humans by nature do not like change. People complain about Mastodon.social being too big to block. So, if people that want to block mastodon.social due to what they believe is poor content moderation but feel they can’t because of its size how likely that people would find it “easy” to move to another instance ?
Nos.social is one, there is https://github.com/atrifat/nostr-filter-relay amongst other tools integrated into some relays.
You said that like that’s been reality, I’m not going based on simply what’s possible but what’s happened when instances suddenly shutdown
If the same came be achieved why hasn’t it been? It is a matter of individualism. People often see instances as communities, I don’t agree with this assessment with the exception of coop and special interest instances.
