Not sure where you got your info, but they don't make any money on the Fire, they are pushing it to drive content and build their customer base. They know that once you have the Fire, you'll buy ebooks, music, etc. from them...it's almost a loss leader, but it's anything but a profit maximizer.

Marginal cost equals marginal revenue??? (Not sure what your getting at) That doesn't lead to maximization of anything.
