I agree with all your points which is probably reflected in the fact I'm strongly anti-centrally planned economically and more towards free market.
However, the free market gives people the option to hate on a company in regards to the ethical practices and how it impacts the sub-culture they are a part of; a vote with your dollar if you will. True, Burton's expansive growth probably made the market big enough to get lots of people on this very message board into the game. But lots of their practices are things people don't want: forcing orders of large volumes so that shops can't diversify their limited budgets among several brands, trying to "patent" snowboarding among others.
I'm not saying I necessarily agree or disagree with those tactics, but there are people that do and choose not to buy Burton because of it and I respect their decision to vote with their dollar. It is better, after all, than resorting to governmental intervertion with commercial controls.
