Not that AliExpress is much better with counterfeit, but it is the "fresh" contender to the West. There might be a movement away from Amazon's core business as AliExpress / Ali* expand here.
I think you're missing the point. The point is you're going to get crappy counterfeits on Amazon, so it's better to just buy them on Ali where you'll get them cheaper.
In fact, Ali does let you choose the seller of the item, and lets you contact him as much as you want before the transaction. So, no, Ali does this better than Amazon.
