What did corporations ever do for you... except build your home, provide your transportation, keep your money safe, provide your medical care, provide your food and provide you with employment?
LOL! He has mistaken "pluralization" with "possessive". Too funny. Writing Style Guide, Identity Standards, Illinois at the University of Illinois at Urbana-Champaign: "Use an apostrophe followed by an s when indicating the possessive for names, even when the person’s name ends in s. Example: The Stevens’s dog, Illinois's football team."
It's especially hilarious that he doesn't even know the possessive form for the state in which he lives! The irony is that his own state's (or should that be states or states') university shows the correct form. Hey, Moron Joe, the next time you try to correct someone, please try to know what the hell you're talking about! "Pluralization" indeed!
