Dreamworks is producing a sensationalized, awful movie about Wikileaks and Julian Assange.

Sadly, knowledge of such rights have been eroded over the years by the repeated claims of copyright maximalists, who would have you believe that you must beg to refer to us in your film -- or even that you would be beholden to us if, for instance, you parodied our disrespectful attitude to your concerns with the following image, which includes both of our identifying marks, the Noisebridge(TM) circuit, and the Unicorn Pissing A Rainbow(TM).
Such a position is lunacy and a genuine threat to free speech and the first amendment. You should exercise all of your fair use rights freely and without fear.
