This post brings up this interesting divide on how you price any of these services. In particular, with software (and movies, and whatever), we know that the marginal cost of producing another copy is low if not zero, and hence in some sense intellectual property can be priced arbitrarily by creators, since there aren't nice curves to determine pricing. This is often the same argument for why IP protection is reasonable.

At the same time, clearly this is not the case for something like EC2, where the marginal cost for another machine isn't necessarily 0, but it is true for Dynamo in some sense. Are we in a world where one can't choose to mix the model?
