Physical books are not the same as digital books.
A corporation cannot replace physical books for free because it will cost them money to print the books, bind them, and mail them to his house. A corporation can replace digital data for free because the data already exists and the delivery infrastructure is in place. If they will not honor his Fictionwise purchases, then they are defrauding him, not the other way around.
I would like to call Analogy Police on this whole thread. Digital books are NOT physical books and
all analogies that hinge on physical books are therefore not applicable. IMHO.
