It didn't come from a lab in Wuhan, it was first discovered in Wuhan but was already going around in Italy for months at that point based on waste samples.

The point was that we have just as much evidence to say it came from Detrick as we do to say it came from a Chinese lab. It most likely didn't come from either, but only one of these conspiracies gets pushed. If you provide any pushback that maybe China isn't responsible for COVID you get met with "well they would lie and cover it up, so I might as well be right"
