"sharedInbox endpoints SHOULD also be publicly readable OrderedCollection objects containing objects addressed to the Public special collection..."
w3.org/TR/activitypub/#sharedI…
I disagree with this SHOULD, would downgrade to a MAY.
Minor, mainly because consider a small instance, whose users do not show their Following collections, this could basically leak who the follows are.
That said, I haven't found any Software that does have a publicly readable sharedInbox!
ActivityPub
The ActivityPub protocol is a decentralized social networking protocol based upon the [ActivityStreams] 2.0 data format.www.w3.org

in reply to django • • •W3C ActivityPub is not of high enough quality for the RFC 2119 words to make sense in it.
It is fine to use it as a primer for how stuff works. However, reading it and drawing conclusions on how the Fediverse works is mostly a lost cause.
