I am still confused how people think that it being an accidental "lab leak" is any more damning of the role China played in the initial outbreak. China made a lot of mistakes and also kept other countries in the dark for way too long no matter the origin. It can also serve as a warning against authoritarian models of rule.
My criticism doesn't mean I think we shouldn't investigate the origins either. It is in the world's public interest to err on the side of knowing too much so that maybe the chance of this happening again is reduced.
I have no qualms about China conducting research in this regard, other countries are doing it too and we would be naive to think otherwise. However, if it is proven to be true that gain of function research was being conducted at the Wuhan laboratory, it highlights the sheer stupidity of the government in thinking they could build a military bio-weapons research laboratory in the heart of a major city center. Western nations that do have such facilities place them far away from high-density urban populations, precisely as a last-ditch measure to mitigate the impact of an (eventual) breach.
It's worse for the CCP if it boils down to incompetence rather than malice. Becoming a laughingstock of the world and not being taken seriously is perhaps their deepest fear.
Incompetence? I think the regime came out of this pretty well. They’ve completely disrupted literally every country in the world, and China itself has been only marginally affected, lacking any of the truly large waves that devastated the US and India.
