You and Samsmart both link the same blog entry. I did read it, and I'm not seeing any explanation.
There is no available means by which any government could "take over the internet", not that I can see. A government could order that no server on its land contain a certain catagorey of information, I suppose, but I don't see how they'd enforce that and I don't see what good it'd do, since off-shore servers would still have it.
Or, like Australia is now trying, a government could order all the ISPs that serve its residents from carrying any blacklisted site, but obviously, this would be very hard to police and wouldn't prevent the "bad information" from reaching its residents by another site.

So, mechanically, I don't see how it could be done. Constitutionally, I don't see how Lieberman's plan would work unless Google volunteers to implement it, as this "terrorist" speech is nonetheless protected unless and until it rises to the level of a criminal conspiracy.
I think you've allowed a hysteric in the blogosphere to "warn" you about a nonexistant threat.
In 1917, President Woodrow Wilson, during his second term in office, joined in the Great War on the side of Great Britain and France. This despite the fact that Wilson won re-election by campaigning that he kept the United States out of the war in Europe when it started in 1914.
Now this isn't taught very much in history classes, but while the 50's had what is known as the Red Scare, it was not the first. Rather, the First Red Scare occurred from 1919-1920. This is because in the decade previous, socialist, communist, and anarchist political agitators from Europe were exiled and made their way to the United States. This was how Marxist ideology traveled from Europe to the United States.
One of the aspects of Marxism and it's children philosophies is that warfare is a corrupt practice that exploits the people so that government and corporate elites can profit. That is that government leaders use nationalism to create false difference between the common people of different nations. In this way, leaders use fear to exploit the masses and maintain control. Corporations use military force to take over natural resources from others and exploit them themselves for their own profits.
Socialists, communists, and anarchists in the United States protested against the Great War on these grounds. One of these was Helen Keller, the woman who grew up blind, deaf, and mute. She was a socialist to agitate for worker rights, as most of the disabled at the time were so because of occupational accidents.
Another notable socialist at this time was Eugene V. Debs. In fact, he ran for President 4 times as the candidate for the Socialist Party of America in 1904, 1908, 1912, and 1920. In fact, he ran his last campaign from prison.
In order to deal with all these protests at entering the Great War, Congress passed the Espionage Act of 1917. It originally prohibited any attempt to interfere with military operations, to support U.S. enemies during wartime, to promote insubordination in the military, or to interfere with military recruitment.
Many socialists, communists, and anarchists in the United States were arrested under this law. They were arrested for protesting the Great War and for writing, publishing, and distributing pamphlets denouncing U.S. entrance into the war in Europe.
Eugene V. Debs was arrested under this law as well for a speech he made in Canton, Ohio, in June of 1918 in which he urged people to resist the military draft. He was convicted and sentenced to serve 10 years in prison. During his appeal, the Supreme Court upheld Debs' conviction because his urging of people to resist the military draft was an interference with military recruitment.
In December of 1921, President Warren G. Harding commuted Debs' sentence to time served, citing Debs' elderly age and poor health as the reason why.
So Debs was a political figure imprisoned for speaking out against the government and the military, and this nearly a century ago.
And this law is still on the books.
So if it happened once it can happen again. Especially in the age of our Eternal War on Global Terror. And especially when a terrorist can be labeled as such simply because he was a bystander killed in a drone strike that targeted a suspect - not a convict but a suspect - and was retroactively labeled as such so the paperwork doesn't list any collateral damage.
