Concentration of media ownership has not been a constant factor over the past several decades and several laws have been changed to alter this reality in that time frame. As the purveyors of news get bought up and consolidated, it has almost certainly made this "information control" problem worse.

"The government is spying on you" is not exceptionally complicated or technical. The fourth amendment is widely known and understood.
The media was complicit in the coverup until it could be ignored no longer. They did the opposite of what an honest news media is supposed to do, and helped suppress one of the decades biggest news stories. That certainly implies something, and directly contradicts the "media just gives people what they want" meme/excuse.
Also, if you think there was "little strong evidence" of what Epstein was up to, I have some good reading for you: https://en.wikipedia.org/wiki/Jeffrey_Epstein#Legal_proceedi...
Simply put, complex stories resonate deeply with a small group and not at all with the majority. What you get from that is the current media landscape. Surveillance is a very complicated technical and moral story that only the smallest group cares about.
