I tend to agree. Having tried the Fediverse twice & each time had my server shut down, had a pretty jank sad partial migration forward path (my old replies kind of being cast into limbo), it just doesn't feel like the fediverse actually has "credible exit" at this point. Decentralized but still semi trapped.

Where-as with Bluesky/ at protocol, most folks are on Bluesky servers, yes. But there's a very strong credible exit case where you can leave the Bluesky servers & just do your own thing. And follow whomever you want to follow.

Bluesky / at proto creates a trust mechanism beyond DNS, creates an identity that can be moved around between hosts or replicated outwards in a verifiable way. I dig ActivityPub, and have been a long time http enjoyer, but it's not ideal imo for social media to need to be so coupled to such strongly DNS based client-server systems.
