The tactics that some companies (I don't know about Amazon) use verge on abusive. I remember hearing about Vodafone being subject to a tax investigation regarding billions they had in accounts in Luxembourg. They hired key people in the investigation to hamper progress. E.g. http://www.accountancyage.com/aa/news/1774186/top-taxman-ditches-civil-service-mobile-giant http://www.accountancyage.com/aa/news/1774186/top-taxman-dit... I think in the end the HMRC took a deal on Vodafone's terms. Nothing illegal but I think you could vilify that behavior.
