For a lot of people this has been the simplest and therefore the most likely explanation for a long time. But what are the implications that now it's a somewhat official position of several US agencies? Will China be asked for reparations? Will they be asked to allow external audits of their labs? Something else?
I think you might find that labs like the one in Wuhan are or were being operated at arms length by US companies and individuals anyway. I doubt much will happen here, maybe some funding cuts
