How decentralized is Bluesky really?

A critical analysis of Bluesky and its protocol, ATProto, arguing that while it serves as a good Twitter replacement with a 'credible exit' strategy, it is not meaningfully decentralized or federated due to its resource-intensive architecture that favors centralization. The author critiques its identity management system and contrasts it with the federated model of ActivityPub, suggesting improvements for both ecosystems to achieve genuine decentralization.

Note

an incredibly thoughtful essay to a simple question with only complicated answers.

a lot to learn as well when it comes to decentralization: zooko's triangle, pet names, DIDs and more and the phrase: "the organization is a future adversary"

there are some deeper level questions though when it comes to social networks: do we need a decentralize social network (is credible exit good enough)? can we have public online social networks that are more healthy than they are costly to society?

what does seem to shine through this conversation though is that decentralization technology has come a long way and continues to thrive and enable applications new and old. it's just that social networks soak up a lot of attention given their status in our society today.
