Some of them are just better at bamboozling schmucks^Wmore naive consumers into becoming their loyal fans and projecting some nobler characteristics onto these corporations, and even identifying with their brand, and becoming an unpaid extension of the corporation's PR department by arguing for them ferociously on online forums.
