As a manufacturer you have no choice. If you make a product that has even moderate distribution it will end up on Amazon. You either take control of your products on Amazon or deal with the consequences: counterfeit goods, used as new, damaged as new, bad customer service, people undercutting all other retail partners, etc.. The customer doesn't care. They will blame you.

It's kind of funny that Amazon actually has a much worse problem with all the things that kept people away from eBay.
