@Nerts The term "federated" doesn't apply to ATproto, that's not how it works.
But Blacksky does go beyond moderation, they also run their own Relay. This gives them the potential to avoid/mitigate censorship by Bluesky's owners, and does theoretically mean they could continue operating even if Bluesky folded.
The core issue ATproto presents for meaningful decentralisation is that running a Relay is extremely resource intensive. Whereas ActivityPub is very accessible for self-hosting.
Excellent point. Check out this exceptional essay from @lrhodes:
@mastodonmigration @Nerts @lrhodes Good article.
My own understanding was originally informed by this article by Christine Lemmer-Webber:
https://dustycloud.org/blog/how-decentralized-is-bluesky/
Although I have also been loosely following more recent developments to bsky since the publication of this article. (e.g. Blacksky's Relay wasn't out back then)
Yes. Christina is the foundation, and really like L.Rhodes introduction of the 'mediated' terminology to characterize the difference. You might also be interested in this thread which attempts to distill some of Christina's points into a more general explanation:
