I think you're under the misconception that Amazon wants to sell Kindles. Amazon doesn't want to make money selling Kindles. They want everyone to have a Kindle. That's why they have smartphone/tablet apps for iOS, Android, Windows (phone and 8) and even (gasp) Blackberry. They don't care what you use, they just want you to buy their stuff for it.
