I don't really understand what is the point fighting over about the lab leak theory. Certainly other virology labs should care, they want to be sure they don't make the same mistake. And certainly covering up any leak would be important to that lab and its immediate allies, but why would so much of the media and so many politicians be so dead-set on it being just a conspiracy theory? I don't think it can be about protecting China in general; China did so many things that made covid worse I don't think one more really makes much difference. The only explanation that makes sense to me is that Trump believed it, and the media and politicians in question had to be diametrically opposed to him, but maybe I'm missing something.

So why should any average people care whether covid escaped the lab in Wuhan or not?
