One quote that shows that non-censorship networks like Freenet are not only useful for mp3 trader, software pirates, and child molesters:

I had been alarmed by the Scientologists’ success at closing down the penet remailer in Finland, and had been personally threatened by bank lawyers who wanted to suppress knowledge of the vulnerabilities of ATM systems. This made me aware of a larger problem: that electronic publications can be easy for the rich and the ruthless to suppress. They are usually kept on just a few servers, whose owners can be sued or coerced. To me, this seemed uncomfortably like books in the Dark Ages: the modern era only started once the printing press enabled seditious thoughts to be spread too widely to ban. The Eternity Service was conceived as a means of putting electronic documents as far outwith the censor’s grasp as possible. (The concern that motivated me has unfortunately now materialised; a recent UK court judgment has found that a newspaper’s online archives can be altered by order of a court to remove a libel.)
