Always be wary of the guy who can't just go to the next sector, but instead has to say his piece about his 'experience'.
It's a disagreement between two people doing a job. The option of not following the pack was two orbits and the usual New Yohhk controller treatment.
Par for the course.
They were given the hand off to the next sector, so just shut up and go. If your boss is going to talk to his boss that's fine - switch over and write the ASR.
The only reason to tell the controller you're reporting the incident is to posture and big yourself up.
Playground stuff.
