I know perfectly good scientists who believe cloth masks are useless. They're in the minority, and I disagree with them, but I can't classify reasonable opinions I disagree with a "misinformation."
I went against the scientific establishment early in the pandemic advocating for masks, when consensus was that they were useless. The evidence and confidence hasn't changed very much since then; the party line has. I'm glad for that change, but it'd be hypocritical of me to complain that I was censored then, and support censorship now.
I'm also glad for freedom-of-speech, and sad when it's taken away. I think it's okay to restrict freedom-of-speech when people lie -- and there's good precedent for that -- but not for differences of opinion, even (and especially) ones I disagree with.
