Can we ever be free of Government?

So the American government is now using its authority squelch payments to WikiLeaks. Americans and foreign citizens alike are being prevented from supporting what is clearly a political organization. This brings up 2 questions.

1) The founding fathers wrote into the constitution a duty to revolt against ones government should it become a tyranny. Given the strengths of the federal government (which was not part of the original constitution) is that now impossible?

2) For the last year or two I have repeatedly heard "intelligence" experts on the radio talking about how the next war will be a cyberwar and we need to fund their departments or it will be the end of the world. Since the leaks from Wikileaks havnt been all that damaging or mindblowing..is it possible someone took a lesson from 911 and just let this leak happen?

Also, in Sweden, things are getting nasty
