It wasn't a fad; it was a moral commitment. I certainly agree that some people are vegan for health reasons, but health was part of why I stopped being vegan: it was harming my health. Not for any of the reasons that anti-vegans trot out, mind you, it was that I was mostly consuming vegan junk food.
My comment was focused on this moral aspect because that's the part of veganism that I was a part of and are familiar with, but I don't think that all vegans are vegans for moral reasons, nor do I think that nobody should be vegan.

I'm not dismissing that at all, in fact, I am arguing that it doesn't actually enable you to retain control. The AGPL is an acknowledgement that the GPL does not go far enough in doing that today, and its failure to gain traction demonstrates that it's not a tactic that works for this purpose. We need new strategies and tactics.
