It's not just that Amazon is not contributing back -- they are not contributing back at scale. They are consuming at scale. They have the scale to distort the established understanding of how a thing works. Like, we've all seen the "have a penny/need a penny" trays at cash registers, and we all understand that sometimes we take or leave things there. Amazon is basically able to send someone to every single cash register in the city and take all the pennies. Sure, maybe that's not explicitly disallowed, but it definitely breaks the model.
