The only exception to the "none of your business" rule is the makeup of the manufacturers labor force. I won't support a company if say it has its merchandise made by a "child-labor camp in Outer Slobovia". I feel I have a right to that knowledge so that I can make an informed decision as to whether I want to do business with such an entity.
So in that case, "Don't ask"/"None of your business" doesn't fly with me.
