I don't think that comment is completely irrelevant. There are already issues of Amazon's own branded being pushed to top, then sponsored listings being pushed to to the top, on top of counterfeit stuff. Now there will be another thing to ignore. I rarely use Amazon because I don't have Prime but if I did, this will certainly annoy me because I am already paying Amazon for the subscription as well as when I buy things, let me get straight to the thing I want to and let it be what I want (read - not fake).
