Social media and mainstream media saw it fit to censor dissenting voices --not those of quacks, we can mostly all agree on minimizing the voices of quacks but shutting down medical professionals and medical academics and so on is very concerning.
The only people they allowed to be wrong about the pandemic were govt officials. They could get it wrong and right it as many times as necessary.
No I don't agree with censoring _any_ voices - precisely because of this issue. The decentralized market of ideas will address the "quacks" in the room, as I don't trust any central authority to do that for me.
If a centralized authority wields power in a way that creates negative consequences, you don't give them _more_ power, or just hope that they'll do the right thing.
But on _short_ timescales, during an emergency when people are emotional, and in a context where media can benefit from amplifying a message whether or not it's true ... we've seen enough people believe some harmful stuff, and sometimes require extra medical attention because of it.
I'm not saying censorship alone is an answer -- but the marketplace of ideas is not functioning as you describe.
