The thing is, just like Backpage, Amazon is disincentivized from stopping the sale of counterfeit goods-- they profit from each and every sale whether it's counterfeit or not.

Their decision to turn a blind eye to fraud could easily have contributed to such a rapid growth rate. Of course their sales doubled; you have to buy two of everything in order to get one that works. Try buying car parts or batteries and you'll see what we're all bitching about.

The noticeable effect hasn't happened yet. Eventually consumers will catch on. People avoid the Dollar Store because the products, while brand-name and cheap, are noticeably subpar in quality. Amazon will develop a similar reputation if they keep this up.
