How? What do you say of the lab-leak hypothesis for COVID?
Also, while "lab leak theory" is often brought up as an example of "the truth" being censored (despite, AFAIK, there being no concrete evidence yet supporting it) it's worth noting that alternative COVID theories were never censored in any meaningful sense, even on mainstream social media. People discussed it, kept discussing it, and discuss it still. I will say I'm confident that when the facts come out one way or another, they will come from the scientific community, not randoms on the internet.
Even if this turns out to be a case of overcorrection by social media platforms (arguably an understandable case, given how much batshit insane stuff was going around back then) it's also a counter-argument to the premise that social media platforms or "Big Tech" control "the narrative" to any significant degree, or really act as the de facto "public square."
The implication of the above comment is that we cannot trust that any claim is misinformation, much less attempt to censor it, because cases of supposed misinformation in the past have turned out to be true. Obviously this is untrue, because actual disinformation and lies do exist, and it is possible to differentiate between them in most cases - even most controversial cases.
