Nah, see my comment above. Those links only tell us that we did not find evidence of the use modern gene-editing technology in the virus. It's misdirection with a straw man.

The lab was breeding viruses the old-fashioned way long before modern gene-editing technology was invented. Bat coronaviruses would be mixed with other viruses and repeatedly passed through human cells. That leaves no evidence in the genome. It looks just like natural selection.

The virus labs in China have had several other dangerous accidents that let viruses get out. Those previous accidents were gotten under control. With this one, we weren't so lucky. I think the lesson is clear: don't screw around making deadly viruses when your biohazard containment is substandard. Maybe just don't attempt it under any conditions.
