Another example of AT Protocol/Bluesky's confusing "open protocol but not really" saga: pretty much all of the web clients listed in their AT Protocol repo don't even have the ability to create an account, only login to an existing one.

So how do you create an account, you ask? You need to get an invite to the Bluesky client to create your account first, then you can use any of these other web clients. That would be like requiring an invite to Damus in order to be able to use any of the nostr web clients.
