That's a fair point. I'm still not ready to call it unethical (in this instance). "Unethical" is not a word that should be used flippantly. I remember a conversation with a person a few years ago who participated in trapping (from a helicopter) antelope for research with a game management agency in a western state. She was genuinely troubled by the number of antelope that died from the stress. I, too, find that troubling. I'm not ready to call that unethical. I don't see any difference between what Hushin did and what the game agency did/does, the differing intent notwithstanding. Both were stressing the animals out in ways I consider unnecessary. "Unethical" is still a word I have trouble using.
Fair chase is a value, not an ethic. Though, it is often called an ethic. Hunting in a high fence ranch violates the fair chase value, but it is hardly unethical. Guys who brag about huge bucks in a high fence have accomplished nothing and have no grounds for their pride, but calling them unethical a stretch.
I think I DO see what the fuss is about, and your comments, in particular help. I think my initial impression was something like "That's not my style, but if this is how they do it down under, how can anyone call it unethical?" If you were disturbed by my apparent inability to see others deem to be obvious, hopefully you can see that my aim is not mere provocation. If I am obtuse, so be it. I'd rather own it than deny it.
