I can guarantee you that Gillette never took multi-billion dollar losses on their razors. It doesn't cost much to give away a few free razors. The handles can't cost more than a few cents to manufacture, it's just stamped metal and plastic.
Anyone can guess. It takes no effort to throw out lots of predictions and have some of them be correct. You are not and wiser or better for having your guesses be right. Even a blind man can hit the bullseye.
