This is about control of information flow, which is key to government control. We the people cannot refuse to be ruled if we don’t know what they are doing to us or planning to do to us. Information is power and more important that ever in the US as we no longer truly have a free press, but a propaganda machine. They have the press, the education system, a lot of religious organizations. If we can’t get the truth somewhere they will rule us much easier than they now do.
No, it is about TAXES. If there were no way to tax blogs, Tor/Freenet users, Freepers, they wouldnt even try as there would be no profit for them.
Then again, they will probably just make it illegal to use Tor or Freenet to begin with. FreeRepublic will probably be "allowed" to stay online, as long as they don't espouse "hate" speech (i.e. the zot thread a few days ago).
