@mariusor @smallcircles @evan No animosity here. However, I’m not sure how to explain it more clearly. I’m referring to C2S as described in chapter 6 of the ActivityPub specification (and the conformance profiles in Section 2.1). It sounded to me like you’re using a more general definition of “client”, which is fine, just different in significant ways (if it only dereferences and renders AP data).
