The problem is that you simply cannot "get the facts right" when the facts do not exist. We did not, and still do not, know where the virus came from.

It's very easy to look back and say "yes well of course this thing was just fake news, but they also censored this other thing that we now know was true!". Either platforms shouldn't censor anything in these situations, or we have to accept the realities of censorship under uncertainty.
