It holds specially for company like Amazon. Do you know how many business Amazon is running on loss? AFAIK they are very liberal in spending in R and D or with long term motive. AWS was once such a project. Who would have though that companies are ready to spend 5x if you add extra services alongside the server. Also, AFAIK Amazon shopping site is not in loss in US. Your suggestion could have made sense if Amazon is using AWS money to strengthen the monopoly, but Amazon shopping is a profitable business, in part due to advertisement.
