I agree. He didn't specifically ask any one person to critique his video in which he demonstrates his woodworking techniques. On the other hand, he did put it out there, presumably in the hope that people would watch and be inspired to copy his methods, or at least learn something. In a sense, it's very similar to releasing a book, film, record album, having an art exhibition or opening a stage play and so on, all of which attract comment and criticism.
Therefore, if what he demonstrates is good, as judged by those that have some sort of standing in the field, that's positive. If he demonstrates dangerous, poor or less than optimally safe techniques (he does) and receives unfavourable criticism and reviews for his efforts, I'd say that's fair. Slainte.
