One way is for the Government to decide a certain body of information that is not allowed to be public knowledge, and when it becomes public, they will attempt to create an "internet information removal button". This obviously will fail, which will pave the way for creation of internet data police to protect and defend us from terrorists by cleansing the internet from sensitive information. The key to own the internet is to demand that it be protected, by government of course, by a data police force.
The final phase of internet takeover occurs by default, big corporations control the government, big corporations decide how the bytes that travel between computers are managed.
