IMO they tried to strike a balance, the existence of Smile helps drive traffic to Amazon and improve their PR, but they make it harder than it should be (you have to use a speciic link, you have to enable push notifications on mobile etc.) so they don't end up having to pay too much. Logically they could have made Smile an option you set once and it's applied forever, but they didn't.
