Look at what Aleksandr Solzhenitsyn wrote about censorship:
Contemporary science knows that suppression of information leads to entropy and total destruction. Suppression of information renders international signatures and agreements illusory; within a muffled zone it costs nothing to reinterpret any agreement, even simpler–to forget it, as though it had never really existed. (Orwell understood this supremely.) A muffled zone is, as it were, populated not by inhabitants of the Earth, but by an expeditionary corps from Mars; the people know nothing intelligent about the rest of the Earth and are prepared to go and trample it down in the holy conviction that they come as “liberators.”
