Yet democracy did not collapse. Why? Because humans have the ability to weigh evidence and discard the nonsense. They have agency. They can decide for themselves what to believe. They don't need you to control their information flow.
"Oh, but now it's different!" the "integrity" people claim. "Now we have to control their conditioning!" No, it's actually not, and no you don't. Now the public has more exposure to views that you don't like. That doesn't mean they swallow them all -- that's just your nightmare of how those other people act.
