AT Protocol
The AT Protocol is a protocol and set of open standards for decentralized publishing and distribution of self-authenticating data within the social web.

When @bsky.app pulls this kind of crap often, whilst also expecting the community to do the heavy-lifting in actually convincing people to try out the AT Protocol... it's really difficult to feel hopeful about the future of Bluesky and its constituents. I imagine many agree with this stance.
