If you click on the "Manifesto" menu item at the group's website, you're taken, somewhat melodramatically, to an essay from the poet John Milton entitled, "Areopagitica: Plea for the Liberty of Unlicensed Printing."

The analogy for Defense Distributed is obvious: Attempting to constrain ideas will always be futile in the long run.
