The only thing that matters when it comes to copyrights is what benefits society. It is not a matter of being rude or not being rude, it is not a matter of morality, it is not a matter of the creator's wishes, it is a matter of ensuring that the general public has access to "science and useful arts." Copyrights were created to promote businesses that make copies of creative works, because in the 18th century that was the best way to spread knowledge and art.

Of course, today we have a much better system for spreading knowledge: the Internet. We should be promoting that, and developing new systems for paying for creative work that are based on using the Internet (and especially peer to peer networks) to spread that work.
