This quote from the article I think illustrates and summarizes the article beautifully:
" So what does the shutdown of library.nu mean? The publishers think it is a great success in the war on piracy; that it will lead to more revenue and more control over who buys what, if not who reads what. The pirates - the people who create and run such sites - think that shutting down library.nu will only lead to a thousand more sites, stronger and better than before. But both are missing the point: the global demand for learning and scholarship is not being met by the contemporary publishing industry. It cannot be, not with the current business models and the prices. The users of library.nu - these barbarians at the gate of the publishing industry and the university - are legion."
