It is clear that Amazon and its management knows that they have a counterfeit problem. How about we all band together and file a class action lawsuit? I am sure there are many millions of people, consumers and businesses, affected by Amazon's active negligence of policing the authenticity of items in their marketplace. I would even say there are probably tons of smoking gun emails between Bezos and staff regarding these issues.
Sometimes the only way to get companies like Amazon to play fair is with the threat of a billion dollar settlement hanging over them. The free market doesn't always work.
