There is no ethical consumption under capitalism.
If people would really live by this, then why even do anything "ethical"?
Don't get me wrong, I don't hate on him (I don't really have the impression that I hated on him at all, that was criticism at best) for going vegetarian, I even said earlier that it's a step in the right direction. If this would have been a video on him going vegetarian, I wouldn't have bothered much. Sure, from a general outside view, vegetarian is better than omnivore, but - again - in the context of the video, he himself shows why there's not much difference between the two.
Also this is not about me, it doesn't even matter whether I'm vegan or not. Don't worry, I don't go around judging people by what they eat, "some of my best friends are vegetarian". But those people usually don't put videos of their eating-habits out there. I'd just have preferred some deeper introspection.
