They're right that they need to actually shift the power away from Bluesky and have users use other servers.
The AT protocol may promise decentralisation and an insurance policy, but that is meaningless if Bluesky the company can stop using the AT protocol and survive it.
As long as the majority of users use the official app and log in to the primary server with their username/password, not the protocol's private key, Bluesky isn't forced to continue using the AT protocol. They still have power to push the enshittify button, block federation, and keep users captive on the official app/website like Musk's X does.
