Why software, data, information, literature and knowledge should be opener and freer?
So called intellectual properties (Information, software etc) are different from conventional properties.
We live in societies under principles of equal opportunity and freedom. Software and knowledge are essential elements for the workings of such societies.
Free sharing of knowledge and information is more productive for a larger number of people than monopolyzing it.
It is also less selfish and cooperative and hence more fun to work and live in societies with easier sharing of knowledge.
