@kaniini There are a couple of good points in here, but this is a really cynical take on AP.
I'd agree it has some blindspots that need to be addressed, but lines such as "In an ideal world, the number of ActivityPub implementations would be zero." is pure hyperbole.
Further I would give it more deference if it presented a viable option as opposed to "this is bad, but I don't know how to do it better"
We gotta do better than this if we are to push forward.
