The thing with Bluesky is that people want to believe.
You can go blue in the face pointing out that the decentralisation simply doesn't exist, and people say "hmm, well, benefit of the doubt, seems like they're working on it..."
You can give lengthy chapter and verse about how this is not a workable design for a decentralised system and it just doesn't get much response.
That's because people want to believe it, and so they do.
@tomw normie vibes about a social network are 90% from the humans they encounter there, 10% the affordances, 0% the tech stack
@moh_kohn A lot of more-technical people are validating the "decentralisation" thing though – treating an (at best) vague aspiration as if it's fact, or giving a bit of a shrug and "no one's figured this out perfectly, seems like they're trying?" Which does play a role in offering people (false) reassurance.
