Often summarized as "don't hurt people and don't take their stuff."

Kind of used it on purpose because vegans would want to apply it to animals and then there would be a debate about whether it should be etc., when that doesn't really matter here -- the vegan libertarian is perfectly entitled to consider factory farms a violation of the principle and use that to condemn them and refuse to patronize them.

We're getting caught up on the semantics of the word "violate." Someone could just as easily accuse the company of not supporting free speech and end up in the same place.
