It's an unfortunate restriction but it is definitely not a "recent change" as the article suggests. It was in their T&C's at least six months ago, I recall seeing it while prototyping an iPhone app that used the Amazon API for some things. If you're a developer who's only just noticed this after months of work then that sucks, but don't try to portray it as a malicious act of Amazon against your project.
