I think there are enough retailers with at least some money, I think this is mostly an issue of business expectations. If AWS were caught sharing your data, with anyone, for any reason, it would be a gigantic mess of a problem. Forget 'competing with Amazon on Amazon' - we're talking about sensitive data of all kinds in every single line of business. It would destroy them. Selling on Amazon, and then having sneaky Amazon PM's use your data against you is bad, but the quasi-same thing would exist in other retailers. Best Buy doesn't sell '3rd Party' so obviously all of their sales data is theirs, and I think that the expectations between '3rd Party' and not '3rd Party' Amazon may just be a little bit blurred. I'm suspicious frankly about the distinction, because Amazon may very well believe that that data is theirs to look at anyhow. But AWS has to be a different story, if not, it's going to hurt.
