One's the kind that affirms existing worldviews, the other asks questions that makes TPTB uncomfortable, like Copernicus's questions about geocentrism.
The term 'disinformation' is also used by TPTB to discredit information that is grounded in observable evidence that goes against narratives that TPTB prefer to maintain.
Accordingly, every single declaration of "misinformation" must be critically evaluated according to available evidence, as the claim itself has been weaponized by bad-faith, self-serving interests of those in positions of power and authority.
The "experts" are frequently wrong, and are not inherently trustworthy. Not every word that slips past their tongue is the truth, the whole truth, and nothing but the truth. They are humans, and like the rest of humans, they lie, they mislead, they are wrong, and some of them and can and do attempt to abuse social consensus mechanisms, including ostracization, to bend public discourse in their favor.
