For what it is worth, they say there is an 81% probability, based on their analysis, that it was a lab leak. That is not the same thing as "claims COVID-19 originated in a lab" - so I think the title is a little misleading - which is probably why the title actually seems to be "What is the source of COVID-19 (SARS-CoV-2)?"

From their Twitter account:
"Probably our most surprising finding to date: COVID-19 has likely originated in a lab.
A probabilistic analysis shows the proximity to a major coronavirus lab and anomalies in the genetic code are too unlikely for SARS-CoV-2 to have developed naturally.
"

The problem here is that "anomalies in the genetic code" is, I believe, their claim, not fact, but presented as a fact along with established facts, which may be interpreted as a deliberate attempt to spread essentially 'fake news'.

I disagree, I don't think it's presented as a fact. They have a detailed analysis on the page. Click the "More" links under the "Chimera" and "Furin cleavage" topics.
No idea how credible that analysis is, but it seems to me like it's done in good faith.
