I heard about this... technically it's not Microsoft.. a Student from Asia currently in America found texts to be extremely expensive so he contacted family overseas who were able to buy the same texts at HALF the price .. they bought a LOT of texts which they sent him.. he resold them and pocketed the money.. The company that issues the books sued saying he cannot resell books he's already paid for legally... even as used... all money he makes selling a book second hand that he paid for and bought legally MUST go to them.. he can't buy a book from them then after he's done with it resell it.. (Used) it's currently in the courts and if he actually loses it would set a precedent making it possible for ANY company to sue and win if you resell anything they sell as a used second hand item without giving them the cash. Basically this would make yard sales, flea markets used car lots.. even Auctions... illegal and subject to a lawsuit. even going to your local comic shop and buying used comics and books a no go...... it would become illegal. Used games would be the same.
