Probably the nightmare authoritarian governments had to deal with, at the advent of the internet brought them to that same conclusion.
And since they realized that, from their perspective, the "information" they were receiving was suspect, all they needed to do was just seed information that was also suspect - just in their favor.
(thats a confusing sentence - from the perspective of a Machiavelli, the naive belief that information is freedom is broken down into a more fine tuned model of information, delivery, reception, uptake and understanding. Their realization is that you can use the internet to hack people, instead of having the internet just hack their regime)
