This is only partially true: in prior media eras, low-quality journalism was notorious for doing what Facebook and Twitter are now. We only notice it because we've come out of an almost century long period in which the most effective broadcast mechanism was regulated by the FCC. This is an accident of engineering; the only reason why the FCC was even allowed to what is blatant government censorship is because of the scarcity of radio spectrum. This died the moment cable news networks became widespread. The only restriction on what, say, Fox News, CNN, or MSNBC can publish is their carriage agreement with the cable companies, which usually just dictates genre, not content. Social media is that but laundered across millions of users who "choose" what to share and like out of what platform algorithms recommend. Prior to television, there was radio, which was also regulated under a similar regime. However, newspapers ruled the roost before that, and they had practically no limits on speech save for extremely weak defamation laws. They also were instrumental in spreading a lot of outright bullshit. "Yellow journalism" is an anagram of "clickbait", after all; and the press were perfectly happy to engage in exactly the same tactics we see today... for pretty much the same reasons. Selling lurid descriptions of political foes and foreign threats makes more money than level-headed explanations of the same controversies. I'm not sure if either scenario could be described as "good". The FCC effectively engaged in a soft censorship regime through the means of spectrum scarcity. This meant that every information passed through [the five filters](https://en.wikipedia.org/wiki/Propaganda_model https://en.wikipedia.org/wiki/Propaganda_model) of ownership, advertising, sourcing, flak, and (at the time) anti-Communism. On the other hand, it's clearly obvious that a good subset of any group of political ideologues is either incapable of or uninterested in making level-headed assessments about themselves. Self-critique is heresy in the eyes of someone more extreme than you are, and we live in times where the extremes might be right about at least one thing.
