If your opinion is already popular, you don't have to be brave: you know it's out there.
If your opinion is unpopular, knowing someone's watching may silence it altogether.
When the society was mostly anti-gay the government machinery was used to hurt these target homosexual groups. Now that society is pro-gay we see government forcing bakers to bake cake for gay weddings.
I will not be surprised if the surveillance mechanism would be used to hurt Libertarians and anti-government people.
Note: I selected the USSR/KGB not for any particular resemblance to current Western intelligence agencies (much more human intelligence and shotgun mics back then) but rather because they seem to me to be the textbook case of the effects of mass, pervasive surveillance over a long time.
For example when I say Donald Trump is representative of majority of conservative base I do not mean majority of conservative base is narcissist and billionaire. I basically mean Trump is pro-Gun, pro-Life, pro-Christian, anti-Gay. Because without those criteria he would not have entered the funnel in first place.
Conservatives or Liberals the current trend among American politicians is "trust us", "bend before authority", I am 100% sure no person can rise to top in American government if he does not conform to these ideas.
Even strong (executive power) leaders like Mr Xi or Mr Putin do not rule over a monolith.
