@adiz That's what I'd like to know. I just recently discovered that FUTO's shit isn't as "open source" as I thought it was, and I remember how LBRY was technically "open source", but designed in such a way to be as unfriendly/unintuitive to 3rd party developers as possible, so now I'm very skeptical of any supposed "decentralized project" until it proves itself.
From what I can find via quick search, atproto is dual-licensed under MIT and Apache 2.0, so it appears to get the gold star of approval from the FSF at least:
https://github.com/bluesky-social/atproto/tree/main?tab=readme-ov-file#license
But I have no idea if they're playing any tricks under the hood. The Guides section of atproto makes reference to self-hosting a "Personal Data Server". But I don't understand any of this enough to be able to figure out if there's any fuckery going on.
