I think it's a reasonable choice for a platform to label, deamplify, or even ban content that is both clearly false and clearly dangerous. Do you think that tweet is both false and dangerous?

I think it's probably false. I don't think information is dangerous, no.

Do you think people should be able to make up their own minds? Unfortunately, all of those actions you mention run contrary to that premise.

I think that's a pretty bad way to frame it.

E.g., look at medical licensing. One could oppose it, on the grounds that people should be able to make up their own minds as to whether somebody is competent to perform surgery on them. Saying that a person can't call themselves a medical doctor is just denying them freedom of speech! Who is the government to come between private parties! Etc, etc.

But in practice that would lead to incredible harm for little gain. I think individual freedom is an important value, but not the only one, and that real-world concerns require balancing values.
