Is Mainstream Media Now The Most Significant Threat To Freedom?

Humanity as a whole knows and understands the nature of governments. We can read history and see how governments operate to get what it wants. The threat of overreaching government and the obsession with control is a problem humanity has dealt with since the beginning of time. It (tyrannical controlling governments) has always been considered the greatest threat to humanity according to history.

Yet we know that governments throughout history have manufactured enemies and portrayed them instead as the ultimate threat; this is the nature of governments: to create "enemies" in order to maintain its power through fear. This known history of government propaganda and lies have, no doubt, accounted for the deaths of billions throughout history. So would it be a silly question to ask, What is the greatest threat to humanity today? Aren't these known facts about government enough to prove the point? I say no it is not, because humanity faces an even greater threat that is now hiding in plain view. The mainstream media propaganda machine, I want to argue is now the greatest threat to all of humanity.
