the ArsTechnica title is harming debate here. a more accurate article would be titled "Amazon will require approval to sell used first-party Nintendo products starting November 1".
i still believe the only way to stop counterfeiting is to stop product mixing in the warehouses. yes, it will mean shipping takes longer -- but until i can be sure that the product i ordered comes from the inventory of the vendor i ordered from, i will treat every vendor on the platform as suspect.
the path they're taking here is a cat-and-mouse game, and i believe it is the beginning of the end for third party selling on amazon.
edit: ArsTechnica has changed their article title. hopefully a moderator will update this post's title.
