I would argue that the very notion that we're somehow dealing with a nefarious, shadowy era of exceptionally pernicious misinformation is itself a form of misinformation. I strongly suspect that the current media and associated tech company obsession with misinformation is largely rooted in a certain very disagreeable politician winning the U.S presidency in 2016 despite all the best efforts of major media sources to convince everyone of what was supposedly best for them, and because these same media/tech interests share a political bent that's currently more dominant in the social sphere, suddenly, misinformation is a boogeyman as never seen before. Evidence to the contrary be damned.
Humans have been misinforming each other and creating echo chambers of rigid thought for as long as we've had culture. On this little has changed except for new additions to the mediums through which we can communicate ideas.
Censorship and restriction of opinions to those that are "verifiable and correct" is such an obvious hole for bad decisions and misuse that support for it should be laughable after decades of seeing just how badly governments and other major authorities can fuck up their notions about what a correct stance on anything really is, and this not to even mention the many, many, many historical examples of official narratives deliberately being manipulated for the sake of control or special interests... Those of you who think modern democratic institutions are somehow immune enough to such things that we should have public free expression monitored and restricted due to misinformation dangers are absurdly naive.
