@jenniferplusplus @julian If we'd remove Mastodon from the picture would the problem go away?
If we had 100% compliant ActivityPub app, whatever that means, would it work with another 100% compliant one? Say podcasting app, badge app, events app and blogging app...
The problem seems to be the undefined or open to interpretation protocol...
Overriding AS object to do something else because your app won't use it doesn't help either...
