Many of the Fediverse's servers are operated by for-profit entities, after all. One of the Fediverse's largest servers (Threads) is owned by Meta. Threads users who feel the bite of Zuckerberg's decision to encourage homophobic, xenophobic and transphobic hate speech will find it easy to escape from Threads: they can set up on any Fediverse server that is federated with Threads and they'll be able to maintain their connections with everyone who stays behind. The existence of for-profit servers in the Fediverse does not ruin the Fediverse (though I wouldn't personally use one of them). The fact that multiple neo-Nazi groups run their own Mastodon servers does not ruin the Fediverse (though I certainly won't use their servers). Not even the fact that Donald Trump's Truth Social is a Mastodon server does anything to ruin the Fediverse (not using that one, either).
