The wuhan and eco-health researchers had already started work on the furin cleavage sites and why would they stop when DARPA blocked it? Funding can’t only come from the US. Did CCP also block this research?
> there is published evidence that the Wuhan Institute of Virology was already engaged in some of the genetic engineering work described in the proposal and that viruses designed in North Carolina could easily be used in China.
Because the Trump administration decided that along with a bunch of other offshore collaboration funding decided to pull the money (America First!). There's a Vincent Racaniello episode on Microbe TV that explained what happened there. I don't remember the episode but here's his channel:

I think if folks would listen more to virologists than the press they'd find out that it's incredibly difficult to engineer new viruses (that's actually in his coursework - also on his channel), but it's also incredibly difficult to create stable "gain of function" (for weaponising) which has been suggested as the source of SARS2 and that whole Wuhan conspiracy theory thing.
