Any society wants some level of censorship, and tends to want it strongly enough to override any Constitution or similar document that says they should have it. Once the system is in place for the kinds of censorship that the majority of society wants, it becomes far easier for someone to expand it. Censorship is so nice when you are in power getting what you want censored that people don't consider what happens when the powers that be no longer represent their interest.
