"The more secretive or unjust an organization is, the more leaks induce fear and paranoia in the leadership and planning coterie. This must result in minimization of efficient internal communications mechanisms (an increase in cognitive 'secrecy tax') and consequent system-wide cognitive decline resulting in decreased ability to hold onto power as the environment demands adaptation.

Hence in a world where leaking is easy, secretive or unjust systems are nonlinearly hit relative to open, just systems. Since unjust systems, by their nature induce opponents, and in many places barely have the upper hand, leaking leaves them exquisitely vulnerable to those who seek to replace them with more open forms of governance."
(Julian Assange, quoted in a long  article on him)

"At last - at long last - the homemade nitroglycerin in the old cypherpunks blast shack has gone off. "
