The problem with posting such videos on the Internet is that some 45.5 hour PPL (or even worse, student pilot) will watch the video and think "I can do that". The pilot in the video may well be stupid or indeed he may well be extremely experienced, having spent much his working life getting trained and paid to fly like that. However, for every expert, there is probably a handful of idiots who will try to emulate.
I wouldn't necessarily be criticising the pilot; I would be questioning the judgement of the individual who posted the video.
