Thank you. This was helpful. The part about #ActivityPub being a protocol was a key piece I was missing.
Your bulleted points examples (1. 2. and a. b.) were very helpful in describing the misunderstanding.
Now I'm starting at https://www.w3.org/TR/activitypub/ to learn more.
Thank you for taking the time to explain.
