I don't think the author is making the mistake you highlight (I know I'm not).
I am not an expert on this subject. If Shooter is, I hope he reads the article and comments. I guess I'm not being direct enough--I'd like to know WHY he thinks "it was, with 100% certainty, not genetically engineered in a lab" when a recent article from a pretty well-respected scientific publication says it is still very much a live question and quotes a former Nobel Laureate as saying:
“When I first saw the furin cleavage site in the viral sequence, with its arginine codons, I said to my wife it was the smoking gun for the origin of the virus,” said David Baltimore, an eminent virologist and former president of CalTech. “These features make a powerful challenge to the idea of a natural origin for SARS2,” he said.
Here's another article I just found detailing the controversy around the BotAS article, with the author noting that
"Other experts that
The Wire Science has corresponded with in the course of its reportage have said that there is no conclusive evidence for any argument about the novel coronavirus’s origins."

I don't know anything about The Wire Science. Maybe it's a conspiracy-theory front but that article sure doesn't read that way. Nor have a I seen anything impugning the motives of David Baltimore. Baltimore could be wrong (Kristian G. Andersen sure thinks so) but for us lay people, it's not very easy to determine that.
