I wish I could say I stopped buying things off Amazon for ethical reasons, but the truth is, I stopped buying because if you look closely at the reviews, you realize that almost everything for sale there is now a scam or a knock-off. This was a slow creep for awhile, but now the problem has grown exponentially. Amazon is what Canal Street was in the 90s - somewhere to buy fakes, stolen goods, and electronics that might catch fire.
Amazon has no interest in fixing this problem, because they know that well over half their "inventory" is now from knockoffs, IP theft and/or bait-and-switch scams. it's almost impossible to find items there anymore that are not fake, whether it's re-packaged hard drives or "pyrex" bowls that explode in the microwave.
One way to look at this, and the way I think Amazon must look at it, is that it's not any worse than a third world night market. The attitude of vendors in, e.g. Phnom Penh or Mexico City markets is that the very fact that stupid Americans think they're going to get "real" goods just proves how much they deserve to be scammed. Amazon is actually helping baffled Americans to finally understand what the third world has always known - unboxing is going to be disappointing. Everything you think is affordable is probably fake, and you can't trust the packaging. Only the rich get actual brand products. As America degrades, people will start to get more savvy and more cynical about this, but right now it's still a newish phenomenon and people are shocked, shocked! to find out the kids toys they bought are full of toxic chemicals that we ourselves shipped overseas for burial or "recycling".
