Free Culture and Free Speech: Why strong and vibrant free culture communities are important for freedom of expression
In the democracies of today freedom of expression is often taken for granted when it is particularly fragile.

The communities that subscribe to the ethos of the Commons are important actors in the creation of the space for free expression.
