All ideas deserve to be refuted, which is why suppression isn't the answer.
As far as the specifics of your claims, I don't think anything has been definitively show to be true regarding the origin of COVID. The paper you linked said that the first hotspot they found were in the wet markets, assuming that's the case, it still doesn't say if it was naturally produced or as part of a "gain of function" research program that was in place at the time.

Check this out for a deeper dive into the intercepts work on corona virus origins. There is no smoking gun, no gotcha moment, in fact it may be a natural origin. My point wasn't that it did happen in a lab leak, but that lab leak turned out to be a viable theory of origin, in spite of how it was portrayed by officials, the media and social media.

The above article is quite a different point of view from what was being said by officials earlier in the pandemic. Again my point isn't to argue lab leak, but to say that if the establishment had it's way, this question would have been wiped away and never investigated. The complexity of the issue would have been lost to the public. That seems like censorship to me. Not book burning, but still censorship.
I 100% agree with your point about amplification though. That's a complication in the issue here because they are incentivised to push divisive, exreme views in order to drive engagement. There is a lot of discussion to be had there.
Regarding my mention of Hunter Biden, I wasn't lamenting that images of him were removed from social media. That's just basic cleaning up of feeds that needs to happen. I mean the fact that despite being verified by the FBI it was treated as bearing all of the hallmarks of Russian mis-information at the behest of other law enforcement agencies. It was then suppressed.
I don't know. You can assume that I'm parroting in bad faith if you want, but I hope you don't.
Isn't the process of refuting something properly by definition critical rather than uncritical? Not all ideas are equal by a long shot, I'm just saying someone shouldn't decide for us which ones we can engage with.
