The Echo is a device of many colors, and with one of those colors it is an Amazon robotic selling machine. I would not be at all surprised if Amazon gets a little spiff (i.e. $$$) from outfits like Spotify and Pandora if someone sets up a new account or even listens to the service through an Echo. Same for Uber reservations made via Echo. I do not believe a lot of these apps are created by Amazon "out of the goodness of their hearts" just for us users; which is fine, Amazon can and should make honest money however they can, so I hope they ARE getting a spiff from these actions.
