These findings aren't smoking gun evidence that "Covid19 probably did not originate from Wuhan after all".
The rumor of the "new pneumonia" was going around between doctors in Wuhan in November 2019 [1]. It's conceivable that there were people who travelled from Wuhan to Europe in November/December, and that the virus was actually in Europe before it was officially found.
Of course it could've come via humans from somewhere else to Wuhan (a good scientist doesn't dismiss hypotheses), but for sure the first outbreak was there.
