I think it is possible to draw some conclusions from the volume discounts AWS is giving on data transfer. From 10TB/month to 150TB/month the price drops $0.09 => $0.05. I don't see how this kind of change in individual customer's volumes would make any difference on how much Amazon pays for the traffic. So I assume it is quite profitable for them to be selling at $0.05 (and lower) and the higher prices are just because smaller customers accept them.
