I think there is a lot of truth to the argument that the customer is best served by a product that is created for the customer. However, I think both Amazon and Google and Apple and Microsoft are in this for the long haul. They probably figure that they are best served by customers who love their products. So while it might be true that in the end, Google wants to sell ads, Amazon wants to sell content and Apple wants to sell hardware, all of them can only do so by satisfying customers. Actually, the difference is rather that since Amazon and Google only use the hardware as a means to another end, they need to exert less control over it and thus offer a wider range of different products.
