Do you believe that private property extends to digital media? Did you know that much copyrighted popular media was appropriated from past works that are now in the public domain. Isaac Newton said that , "If I have seen further [then other men] then it is by standing on the shoulders of giants". We owe much to our common past and shouldn’t forget that we are currently creating the past from which our children will have to be creative.
I remember a conversation about copyright I had in Tunisia a couple of years ago. An IT manager was discussing software licenses and how he was not bothered by using non-licensed software from major North American vendors. He could not understand how these companies could claim software intellectual property rights when the concept of zero, necessary for computing, came from the Arab world and no North American company had ever paid for this IP. So why start charging now?
The open source movement is about making source code freely available, while the Creative Commons (CC) is an organisation that allows individual creators to share their work but still retain certain rights. CC makes it easy to understand copyright and to use licenses that have been vetted by legal counsel in many countries.
