Source?
Do you want to be that mass-media has never been shut down by a large government?
It has happened and can happen again.)
Aren't you the one making claims now? Why does Patio saying that "Governments can't control a worldwide network" need a source, and yet you saying that mass-media(presumably, in this context, mass as in global and not national) has been shut down by large government doesn't? ("mass media" is not the internet, anyway).
Any censorship or control by a government doesn't extend outside the government's jurisdiction. The U.S government couldn't shut down the internet anymore than the chinese government could.
The level of government cooperation required to censor the internet, the amount of agreement, among politicians from varying nations, would be heartwarming if it was at all possible, but the fact is that most politicians in the same country can't agree on most things, to expect all the high-level politicians in a rather large set of country to agree unambiguously not only to censor media but to also be entirely quiet about it is nothing but conspirational thinking.
