"Lies", distortion and bias (opinions) are all part of the human make-up. Real judgement comes from the whole body of imperfect evidence. But when you centralise and continuously consolidate the outlets through which this sea of bias is sifted and filtered (the mainstream) you seize control and you get to craft the message. That has been the foundational relationship between power and people for centuries. Books brought education. Technology will open gates and let anyone and everyone pass through them, carrying whatever information they wish. You're viewing this in terms of replacement rather than revolution. The revolution happened a while back and the stupid, greedy corporations built their empires on the back of it. Now, like all technology (eventually) it is finding its way into the mainstream - hence the great panic in officialdom as they rush about with their silly and impotent censorship pens and worthless ownership decrees. Nothing will flow through a central point, it will flow everywhere and it will be untraceable, uncensorable and unstoppable. Unless the dinosaurs want to shut technology down and bring us back to medieval times. They might, I suppose. They've done it to other countries.
The other possibility in terms of a negative outcome is if the majority has let its self esteem fall so low it demands its chains be restored. That's definitely a possibility. But it would have to be a very high percentage who are that hopeless.
