Sure there are a number of competitors, but iTunes still dominates when it comes to dollar share of music purchases. Regardless of their intention, Apple has certainly "squeezed out" most of the competition, and remains the dominant platform for purchasing music. Similarly, there are still options outside of Amazon when it comes to eBooks. There's Nook, Kobo, iBooks, Google Books, Sony, and others. So Amazon's desire to make profit hasn't completely wiped out the market. So this argument does not really hold in either direction...
