Big question, Why ATProtocol from #BlueSkySocial #PBC’s mouth instead of Mastodon and ActivityPub?:

“Why not use ActivityPub? #ActivityPub is a federated social networking technology popularized by #Mastodon.

Account #portability is a major reason why we chose to build a separate protocol. We consider portability to be crucial because it protects #users from sudden bans, server shutdowns, and policy disagreements. Our #solution for portability requires both signed data repositories and #DIDs, neither of which are easy to retrofit into ActivityPub. The migration #tools for ActivityPub are comparatively limited; they require the original server to provide a redirect and cannot migrate the user's previous data.

Another major reason is #scalability. #ActivityPub depends heavily on delivering messages between a wide network of small-to-medium sized nodes, which can cause individual #nodes to be flooded with traffic and generally struggles to provide global views of #activity.”

Short version, WE CANT CONTROL YOU.
