@volts.wtf There's the takeover from above, with the consolidation of media empires, Rupert Murdoch, etc.
And then there were the networks of fascist activists who disrupt any forum that isn't aggressively moderated.
We knew, in the "blogosphere" era, that Newt Gingrich's wing of the Republicans, Frontpage Magazine, among others, were actively coordinating attacks on liberal and left bloggers. They had newsletters where they discussed talking points which they'd spam widely.
@volts.wtf I think people are afraid of sounding like conspiracy nuts, and I can understand that.
Everyone should watch the first episode of 'Century of the Self', to understand the science behind modern political propaganda.
Then read three works by David Brock: Confessions of a Right-Wing Hit Man (Esquire mag), Blinded by the Right, and The Republican Noise Machine, which detail the GOP media operation since Nixon's time.

Lewis Powell: "Letter to the U.S. Chamber of Commerce", 1971. Originally intended to be secret, it eventually came out.
He proposed buying and controlling media, attacking higher education as well as other processes intended to push public opinion rightward.
Powell went on to be a Supreme Court justice.
Robert Bork in the1980's defanged antitrust enforcement, encouraging the merger and acquisition spree that continues today.
All intended to limit power of citizens.
