The most interesting part of the HN discussion is not about the definition of what Amazon is doing, but the occasional misunderstanding of how large brick and mortar retail businesses operate at scale (see: buying shelf space/payment dependant on sales/etc).
There are lots of folks on here that understand what Amazon is doing, less who understand retail businesses mechanisms.
I'm not sure what Amazon is doing is legal (def will vary widely between the eu and us markets), but it is another interesting example of how doing something at scale can be perceived as fundamentally different then when it's done in a smaller way (especially as it pertains to privacy).
