This latest article is not as coherent and a bit all over the place, but Amazon’s response is not helping either. Amazon says “Offering products inspired by the trends to which customers are responding is a common practice across the retail industry.” Amazon needs to nurture trust in its ecosystem but seems to be doing the opposite.
I don’t actually see any rampant issues except for access to product search data. Amazon is the dominant leader of the product search market (above Google and others). As a sign of good faith in building trust, Amazon could make (aggregated, anonymous) search data available and offer “Amazon Trends” like Google Trends. Needless to say, third-party sellers may be offered a more in-depth access.
