We are talking about the threats in DN. 

I think we should be focusing on the things that are special to DN which is a technology that adds certain properties to a general network. I assume the protection of the general network using the normal techniques is a given.

Passively looking at the contents is about privacy and technical surveillance to intervene more effectively.

Privacy obviously applies to a general network, and I take it as read that we protect against this. However this document is about DN, and I cannot see what the privacy concerns are about the DN specifics.

However I am not sure on-path is the right term. MITM normally implies an entity that can modify traffic in flight, whereas an on path attacker may simply be an observer.
