The quoted DARPA official is slagging EcoHealth Alliance for "willing to get on an Air China jet, eat terrible food, and stay in bad hotels", which doesn't sound like it has much if anything to do with science.

For what it's worth, to me Dazsak and EcoHealth sound sketchy as fuck and it's pretty obvious the WIV is frantically trying to cover its ass. However, this is a national pastime in China when anything goes wrong (exhibit A: https://en.wikipedia.org/wiki/Wenzhou_train_collision), and thus doesn't necessarily mean the WIV is directly responsible.
