the main contention is a disconnect between #ActivityPub as a spec and #fediverse as a protocol/network. a lot of problems cited were with the fediverse as implemented, wishful thinking about what could be changed in spec, many backwards-incompatible, mostly in service of making fediverse impl less painful.

there is a recurring refrain about implementers deciding they don't care to implement AP as specified, and that this indicates a problem with the spec, not a problem with implementers.
