Your starting point for understanding disinformation.

Glenn Greenwald's excellent take:

All that said, there is a core truth — an unintentional one — that lies at the crux of this elite war on "disinformation." It is absolutely true that U.S. political discourse is drowning in deliberate disinformation campaigns and lies. It is also true that this disinformation epidemic is a serious menace, a toxic plague on our democracy and society. That part they have right.

Where they have gone wrong — very, very wrong — is how they have identified the most harmful sources of this disinformation. It does not emanate primarily from Trump boomers on Facebook or dark web QAnon groups or mischievous and transgressive teenagers on 4Chan. Ordinary citizens are obviously as capable as anyone of believing and spreading false assertions. But the far more damaging, destructive, organized and coordinated disinformation campaigns come from major corporate media outlets themselves and their security-state partners — particularly the corporate outlets that most vocally and flamboyantly claim to be so profoundly concerned about disinformation that they want to censor the internet in the name of stopping it. They are the ones who spent the last five years flooding the country with demented CIA-constructed conspiracies about a Kremlin takeover of the U.S. using clandestine sexual blackmail over the president and hallucinating Russian agents hiding under every bed; so many fabrications were disseminated under the rubric of that fairy tale that it is genuinely hard to choose the worst.
