I'm not a virologist (nor a conspiracy theorist, by the way), but every time I read articles about the origin of covid being settled, I feel like the writer is trying to push an agenda. Yes they give perfectly sound logical reasoning, sure, but that's all it is. The counter view obviously will continue to be driven by the location of the origin.
Edit: and by the way, the autism-caused-by-vaccines theory is not solely the result of a bad study getting too much attention. It is similarly the result of people making conclusions from big coincidences. In this case the onset of autism (at least the age when symptoms get bad) is commonly around the same age that children get vaccinated. The study didn't just make that idea up, they were trying to validate a belief that was already held relatively widely.
This kind of skew between public perception and scientific consensus can create a siege mentality, because it's easy to find someone who has been convinced by some media subculture that something is self-evidently true in spite of reams of evidence to the contrary. As in the vaccination-autism connection situation, all it can take is one scientific study, subsequently debunked, to give an entire movement the validation they need to completely ignore an enormous consensus with plenty of data to back it up.
BTW (need to add this disclaimer on the internets, I often forget) I'm not disagreeing with you, just riffing off your comment with some more thoughts.
