Well, the fact that this has so many upvotes, sort of contradicts you. Some portion of people (maybe 15 or 20)% had brand-trust in amazon that their "choice" products were a service to the purchaser.
With that disproven, those same people (presumably the ones who were most trusting of Amazon) now have been bitten and are forced to reevaluate Amazon's honesty and Amazon's reputability. I imagine those upvoting this topic are the very 10-15% who find this behavior shocking and potentially self-destructive of amazon.
