Well, first off - it's only advertising if the links are added in for this purpose - as mentioned in the article. If there are Amazon links already on Wikipedia, and I'm sure there are some, that's arguably alright to add affiliate links onto. However, the issue is that people may begin adding more and more Amazon links onto articles to try and get more money for Wikipedia - then it becomes advertising. Finally, your second point - I like better service and I like lower prices, but I dislike DRM and I dislike companies that obtain monopolies and exert control. It worries me that, in future, you will get kindle-only books or books that can only be bought with DRM. Books that in 50 years time may be lost forever. It really saddens me that we are giving away control of our media. Anyway - that's a rant for another article! Just for perspective: I really support DuckDuckGo using affiliate links with Amazon (and perhaps other retailers too) - I think that's a great way of generating money for the service without resorting to adverts. However, on Wikipedia, I don't think it should be used.
