Regarding Covid, the "Lab Leak hypothesis" was also banned as misinformation, despite some variants of it having verifiable (albeit inconclusive) information.

It was then unbanned after the Biden administration decided it was actually plausible enough to be worth a look.

So...your characterization of "misinformation" seems reasonable in principle, but there seems a disparity between that and how it's applied in practice.

Benevolent dictatorships are a wonderful way to run a society, if you can find yourself a benevolent dictator who will stay benevolent. This has proven pretty much impossible, though, so we take a more conservative approach to granting power. We recognize the abuses that non-benevolent dictators inflict, and strike a balance which is quite far on the "prevent abuse of power" side.

Do you think the state of affairs is particularly different for misinformation?
