I did read quite a bit of it. The article is a typical "Gish Gallop", just throwing out questions hoping that the reader will not bother following up on any of them, and end up believing because of the sheer weight of argumentation.
there are a ton of solid arguments. For me the most important one is: The director of the Wuhan BSL4 lab that was dealing with SARS coronaviruses said that the first thing she thought was "omg, I hope it's not from our lab". That kills ALL arguments about this being a conspiracy theory that cannot happen and is debunked. It is apparently a valid possibility. Now, let's take her word for it when she says "I swear it wasn't from us". Sounds very scientific yeah
