I realize they're trying, but Amazon is clearly failing to control the tide of fakes that is infesting their storefront. I find that for almost anything I search for, the knockoff/fake is actually the Amazon "recommended" item.
Probably this is because a non-trivial part of their revenue comes from the dark patterns and scams that make their whole site feel so much like the kind of flea market where you're pretty sure some of the stuff's stolen and if you ask around one of the vendors can get you some Oxy, but you wouldn't buy it from them even if you wanted it because it'd probably be fake. IOW I'm pretty sure their site and fortune's based largely on crime and generally anti-social behavior, else they'd surely have stopped it by now.
Honestly, isn't that what's at the base of the culture of 'disruption'? Look at Uber - let's take an established, regulated industry and just ignore the regulations long enough that we're everywhere and they can't shut us down.
Honestly, when I hear the word 'disrupt', I immediately think of shady, anti-social behavior.
I bought a new mp3 player from Fry's once which, oddly enough, turned out to be stocked with a sizeable music library already.
I'd still be pretty comfortable buying a candy bar from them though.
In the case of Amazon, we know them to have a long and extensive history of selling a wide variety of counterfeit products. There is not nearly as much ambiguity to the situation. Elsewhere in this discussion the comparison to a flee market has been made, and I think that describes it well.
