Extremism and quackery got plenty of exposure in the 17th to 20th century "media model". Even anti-free-speech attitudes themselves are not new. There's nothing new under the sun.
If anything, the extremism and quackery of today are far milder than those of the past - even the relatively-recent past. The wisdom of crowds is self-correcting, if allowed to self-correct.
