After 3 pages, sorry If I am repeating this. But it is true , that COpyright and patents are a hindrance for growth. I mean, the main aim of the world is to move forward and grow, and using on innovations from other people. If you copyright something, then that basically hinders that growth.
Here is also an interesting video/article: http://www.bloomberg.com/news/videos/b/6888f36d-5487-4bfb-b670-32c581f1d2ce
Can't find the similar article I read.
