Some say Coca-cola is owned by freemasons, some say Pepsi-Co is owned by devil worshippers, some say Starbucks Coffee is owned by malevolent unsanitary midgets who use peeling skin from a hobo's unwiped bum to flavor their lattes. Damn businessmen!
OT: You could go through all "certified" integrity-corruptable news stories maybe to find your corporation the more "publiclly evil", though I imagine this is all in good, mindless fun. Pepsi is more evil because they are negotiating more contracts to serve their beverages in my local pizza-places then Coca-cola is. That's all I can give you.
