Internet is going to become heavily censored, like it or not.
Why?
Simple, it's extremely powerful communication and propaganda tool (as we have seen in Arabic Spring) to be ignored in the future by governments all around the planet. It's a weapon! Think gun laws and how heavily gun ownership is regulated since early 20th century.
I don't think that aforementioned criminal activities (childporn, hacking, fraud, etc ...) are the main driving force behind increased voices for internet regulation. Governments are afraid of uncensored social networking of their subjects, simple as that.
Oh, and internet usage can create addiction like alcohol, drugs, gambling, so it's perfect ground for some extra taxing :smilewink:
At the moment all secret services (yes, the "democratic" ones, too) in the world are heavily involved in internet monitoring ...
Be afraid, be very afraid ... :alien:
