I don't know how to define what is "misinformation" but I could surely call out a couple examples. Maybe we can figure out what makes them misinformation.

1) 5G causes COVID-19 2) COVID-19 doesn't exist, i.e. it's all a hoax 3) Aquarium cleaning solution is a cure for COVID

I don't know what makes those different from "masks are worthless" but they seem qualitatively different. Maybe for a couple of reasons.

Maybe for #1, there's no plausible mechanism of action linking 5G and covid. But the people claim there is! Using a nested series of faulty reasoning and unreproduceable evidence to back it up.

Maybe for #2, there's no observable evidence that it's a hoax, i.e. people claiming otherwise are doing so with no supporting evidence, only reasoning that they (subjectively) do not trust government or media, therefore their claim is supportable.

But I don't know. I don't think the answer is that it's unknowable (which you may or may not have been getting at).

For me misinformation as a characteristic is a big umbrella, that the discretion for it depends on the measurer. Which makes it an unreliable characteristic to censor content by.

As an example of things that can follow into the misinformation umbrella parody, humour, good/bad science, good/bad journalism, misinterpretation of intent, paranormal reports, religion. It done for the greater good. People have done surgeries in their garage, I can't believe it's from lack of credible information, and that making a general policy from the exception is a sign of a bad design.
