There are two things going on here:

- There's strong evidence that it's not bioengineered; scientists used very strong and convincing language here.

- There was initially hope of finding the zoonotic reservoir; scientists used couched language here to subtly detangle a natural virus vs. a natural virus that had adapted to passage in cell culture in a lab, and had priors assuming a zoonotic source would be found.

Guess which language journalists glommed onto.
