I would say, Jay's explanation makes the most sense to me. Which reminds me of the story: "Hey, don't buy that ShopRite, Stop & Shop, PathMark, whatever - cereal, toothpaste, PainKiller, bleach, Olive Oil, you name). It 's not as good as the name brands!! Yeah, sure, all those supermarkets have their own huge factories making those products just for them, And, the box shapes, exact ingredient, exact weight, exact calories, same taste, etc, just happen to be exactly the same!!
