What should happen if an Like activity uses direct addressing (no as:Public)? It seems the intent is that you want to send a "private" Like notification to the activity recipients. Should the public like count be incremented or not as a side-effect? If not, Like counts would be dependent on the authorization of the actor fetching an AP object. I hope ActivityPub 2.0 has better authorization guidance.
