Your stuff is yours. You can put anyone's milk on your cereal, not just milk that Kellogg's endorses. If the milk you choose is sour and you have to pour your cereal down the toilet, that's too bad, but it doesn't mean that Kellogg's should have the right to shame you for having the temerity to choose milk you preferred, and it *certainly* doesn't militate for DMCA-style enforcement to coerce you to use Kellogg's official milk in the name of protecting you from food wastage.
