Compare and contrast the following phenomena:
When I think of the turning points in the history of mankind, I see great advances in information dispersal. For example the printing press, which made books available to a much larger audience than before. Through the requisite literacy, this was a crucial step in the general intellectual development.
The Internet is pretty much the end to mankind's quest for the universal library. So what do we do with it? Censor and control the hell out of it.
Of course, the desires of a single person and the ruling classes are rarely aligned. What religions have done to the sex lives of people, the media giants are now doing to their drive to spread information.
But to what ends? Surely the spread of information and knowledge is for the good of people, as is the rule "go forth and multiply" for the survival of a species.
Of course, censorship of free information from people is good for the governments. But even with the entertainment industry, things could be more about censorship than money: Make it hard and expensive to spread information, so only the wealthy ones can keep doing it. Maintain the cultural hegemony of Mickey Mouse.
This is somewhat similar to how many religions deal with sex: keep it restricted, but go forth and multiply like drunken rabbits on Viagra within those limits. Every sperm is sacred.
