The lab leak theory doesn't necessarily imply engineering or contradict a zoonotic origin.

I couldn't follow this personally. It seems to be scattered notes pasted into a Google Doc saved to PDF on Google Drive without a whole lot of journalistic narration. I see what sounds like science but I cannot for the life of me find where those intermediate number came from. But, here's the conclusion, as a summary: "In my Bayesian analysis, modeled after Michael Weissman's analysis I concluded PO(LL) / PO(ZO) = 1.7E-3 The product of my updates, I concluded P(LL) / P(ZO) = 2.125 The final, then is PO(LL) / PO(ZO) * P(LL) / P(ZO) = 3.6-3 I concluded that there is approximately a 1 in 300 chance that SARS-CoV-2 was the result of a lab leak." That is the structure of Bayes theorem, but I have no idea where the numbers came from.

This is just an argument from faith and predisposition at this point. All the positions people have taken have now calcified into non-falsifiable nonsense.

For myself: if we were going to get evidence for WIV having engineered a pandemic virus we'd have had it long before now. Biologists aren't spies, and they're not good at coverups. Someone would have blabbed or lost a laptop or took a position at a western university and then fingered their coworkers, etc... Sure, it could have been manufactured, but it probably wasn't.
