The issue is also a management reacting to a post of Facebook and following the media hype, by (apparently ) sanctioning the Captain of that flight, while the real one that would need to be disciplined is the F/O taking that video and releasing it to the public.
In my world, and in most ATC units , Smartphones and tablets are banned from Ops rooms and taking photos/video strictly prohibited, and posting them on Internet or given to media ( same thing) would lead to serious disciplinary action . It it not what you filmed, it is about who took the shots.
