My guess is that many have just about given up in finding a naturally occurring intermediary. It has been months now. And if the Chinese already know the intermediary was the lab, they already know it will never be found.
Their PR yesterday that the WHO couldn’t prove the lab didn’t concoct or leak it, which is hardly a flat denial. Add to that the fact that Chinese labs have notoriously leaked Corona Viruses before, and Occam’s Razor is starting to kick in.
There was a dr who fell on the sword for an ... ahem...accidental Sars leak. Story is hard to find but i posted it once
If bat lady is alive she may be the one that falls on the sword
