>they're so proud that they're actually decentralized and self hosted (even tho most users are on mastadon.social)
Sorry, is any of that supposed to be wrong? People who use a decentralised platform aren't going to be fans of a new, mostly-centralised platform, I don't see how that's being sore losers. I also don't think most people on the Fediverse expect mainstream adoption any time soon, and many don't want it either.
They’re saying the talk about being distributed but generally congregate heavily on one (centralized) instance
Being on a large instance doesn't mean you don't care about decentralisation, you can still choose to migrate to a different instance if you want. The whole point is you're not locked in to one vendor and you can move if you want to, not that everyone should have to live on their own island
Sure… but you can see why it makes it hard to care (and in particular stomach the complexity of coming onboard)
