I do.  They want to own the "@" symbol.  And at:// is the scheme that they want, which the IETF is not too happy about.  Obviously they are quite late to that party, so it can only end up as a mess.  A Bold Protocol.   

 What do you mean by saying they want “at://“? 

 They want that to be the name of their protocol scheme.  Like http:// and they are trying to register that at the IETF who manages these things. 

 Ok go it. So they’re looking for at://user.bsky.com to go directly to that users profile
