Simple. Freedom of speech is, and always will be, a threat to governmental narratives and effective propaganda campaigns.
Notice this pic as an example.
Once enough Americans realize they are being played like pawns, that the government really could care less about them, that governments only care about their special interests and central banks that line their pockets with trillions of dollars while we slave away earning a living or end up mutilated or dead in their never ending conquest for global hegemony, Americans will start to think twice about fighting for the special interests and government that are screwing them over 24/7. People will start to "opt out", some will move more rural and become preppers and homesteaders, others will join peace movements (like what happened en mass in the 60s and early 70s), many will boycott the draft, some will even refuse to pay taxes and simply sponge off welfare. That's not a bad thing honestly, for the people that is. However, it is very bad for the government, it throws a giant wrench in their mechanical agenda. Therefore the government *HAS TO* crackdown on free speech, so we are all lemmings abiding by their corrupt special interests, so we remain cogs in the slavery machine.
