Free software is built on a paradox. In order to give freedom to users, free software licences use something that takes away freedom – copyright, which is an intellectual monopoly based on limiting people's freedom to share, not enlarging it. That was a brilliant hack when Richard Stallman first came up with it in 1985, with the GNU Emacs General Public Licence, but maybe now it's time to move on.
There are signs of that happening already. Eighteen months ago, people started noting the decline of copyleft licences in favour of more "permissive" ones like Apache and BSD.
