Bluesky has been asymptotically approaching full decentralisation. A few years ago the gap was everything except a decentralised design, then it was AppViews, now it's "tooling and documentation" for the bit of the PKI that only 50 entities have done.

Meanwhile I lost my Mastodon account history because I moved once, couldn't interact with half the network or apps because I was on a non-Mastodon codebase instance, lost my account again because I stopped paying for access to the instance I was on, all classic signs of centralisation.

I think a lot of those users do care but they don't know they've been lying.
