Unfortunately this theory coming out during the Trump era made people knee-jerk shoot it down for political reasons, and you can also say the CCP is very invested in making sure they don't have pie on their face if this ends up being what truly happened.
Compare that to what we know: it's a SARS variant, in a place where SARS outbreaks have already occurred in the past, with DNA showing it came from pangolins, in a place where pangolins are caught, sold, and eaten by people.
Not correct. All previous SARS outbreaks were in a totally different places (~1000 km away).
Prof. Shi (石正丽, the head of the Wuhan virus lab) herself said in her March 2020 interview that she was totally surprised of a SARS outbreak in Wuhan. It is not a location where it was expected.
