Did the author even bother to do basic research before writing this article? Yeah I'm sure that AWS, a 25bil/yr business, is somehow subsidizing consumers for the 123bil/yr retail business that *existed before AWS ever did*. Also apparently Uber is the first IPO for an intractable business model, while they mentioned the Lyft IPO literally sentences before. 
  
 Fucking clowns.

Revenue isn't profit. AWS is profitable, Amazon.com is not. Margins in retail are thin, so subsidizing losses in the retail portion of the business would be doable with AWS.
