Check out 'Inside Wikileaks' by Daniel Ellsberg, a WL cofounder who had a falling out with Assange and founded his own radical transparency platform called OpenLeaks. Brigitta Jonsdottir used to work there too, an Icelandic green.
Wikileaks stated policy and concept used to be:
- Receive, in a way that keeps the leaker anonymous, any and all state secrets that are of public interest
- Publish them after checking authenticity
This constitutes an attack on secrecy as such, not on any particular country or entity.
