Amazon extracts a poor margin out of their $514 billion in sales. Over the past four quarters their operating income margin is a pathetic ~2.4%.

Apple's operating income margin is ~29.4% by comparison. They have a vastly superior business.

Eventually Amazon investors will tire of the terrible stock market returns that present Amazon is generating and the garbage that is retail and they'll demand the company split itself up. That will involve spinning off AWS so investors can realize max value for that (before it's too late and growth slows to a crawl in that space).
