Yeah, bluesky has a bunch of features, notably account portability, which was specifically designed into the ATProtocol.
The purpose of the ATProtocol was never to federate with Activitypub, it was to build a more feature rich and scalable “federated” protocol.
For Ukraine, only NATO membership makes sense to end the war.
There is literally nothing else that can prevent Russia from invading. They broke their word in 2014, then again in 2022, without NATO membership, Ukraine will just get invaded again and again by Russia until it’s a satellite state or fully annexed.
