It is irresponsible, and ESPECIALLY irresponsible to post your free handling videos online imo... because it eggs on other people to try it too, however little experience they may have. If he even just free-handled one or two individuals and specified that he "knows the animal extremely well, and do not try this on your own" or a warning like that, I would be okay with it.
And look, this guy in the link is only 20 years old. One can't honestly believe he is doing this because of his "ability" with them.
