Whenever I come across any language in a license agreement that attempts to limit my fair use rights, I ignore it. Copyright law, both in the United States and abroad, has been twisted beyond recognition. Copyright owners have no less control over their works in a digital format than they did in other formats, and the fact that most western nations (or perhaps just the US) spend more on copyright enforcement and contract litigation than they do on healthcare or feeding and clothing the poor speaks volumes about our misguided priorities.
