Generally speaking, I am pro-copyright. I think people should be protected when they create something. I don't want people to just copy my work and presenting it as their own, but there is something wrong with the current law on copyrights.
Copyright, yes, but reduce the time where the rights are held.
Same goes for patents.
A pharma company spends millions or billions on creating a new drug. They wouldn't if they wouldn't hold the patent's right on it. So we need patents to promote creating inventions. What we do not need is laws that prevents innovations.
Software patents are particularly bad. You spend more time checking if your ideas are patented than actually coming up with the ideas. That is just not right.
Sorry for ranting. I was discussing this with Molegro Mikael just the other day, so it's been on my mind lately.
I really don't know what the right balance is between public domain and copyrights, but I strongly feel that the current situation is just wrong.
