I think that you have missed the point here.
Hamrah is not complaining about ITTV's use of the video, but rather a third party's.
As it would appear from Hamrah's comments that the third party has not licensed this material, then its use would appear certainly to be breach of copyright and there is also a question of potential defamation to be answereds by Four Forces.
The point about educational use is likely to prove a red herring in this context; universities and others use this argument in the context of general copyright, but the ITTV video apparently has a specific copyright notice restricting it's use.
John Fletcher Moulton commented on ethical behaviour that "It is the domain of obedience to the unenforceable"
In this instance the matter would appear to be enforceable and if Hamrah believes that there is an absence of ethics then I support his action in doing something about it.
I am not a professional pilot, but I am a professional and believe that we must support each other in maintaining correct standards of behaviour in commercial life.
