I disagree. It should not be Amazon's business what MacMillan charges for its books (in this case, specifically its e-books). I think this is a slippery slope situation. When Amazon has so much power to throw around, what's the limit of their demands? Today it's pricing, what will it be tomorrow? And the day after? It is rare for any large corporation to avoid abusing any newly acquired power to the utmost extent in seeking advantage for itself. If consumers roll over and don't raise a fuss about Amazon's use of power in this instance, I have little doubt that Amazon will find future uses for its new found power.
