You're constructing an artificial dichotomy of blame here. You're attempting to say that we can only blame the couple or only blame the broadcaster.

Does the general sentiment that 'no one likes a gossiper' only apply to private information?

Example:

   1. I'm with a friend in public
   2. I pick my nose
   3. No one notices but my friend
   4. My friend then shouts at the top of his
      lungs, "Hey everybody! This guy just picked
      his nose."

Are you going to pin a medal on my friend because you dislike people that pick their nose in public?
