Certain misinformation "works", but censorship also "works", so unless you can detect false information with 0.0% bias, that puts the platform's finger on the scale.

I'd much rather deal with information assymetries from individuals within the community than information assymetries from whoever happens to have control over the platforms, and is willing to use censorship.

I'd also like to add that a lot of these misinformation studies ironically wound up using information now accepted to be true or likely (such as that COVID most likely originated from a Chinese lab) as their "misinformation" - so in a way I'm glad that countering with "true" information didn't unilaterally work.
