This is no way exonerates the Wuhan government from possible culpability—indeed government officials did deliberately suppress information—but this investigative opinion doesn’t pass scientific muster. Misinformation.
I think that's true, but it ignores the possibility that the WIV was working with new viruses with unpublished genomes. The WIV routinely organized expeditions to remote bat caves to collect samples. There's naturally some delay between sampling, sequencing, and publishing, no conspiracy required. For example, RaTG13, the closest known animal virus to SARS-CoV-2, was collected by the WIV in 2013 but published only after the start of the pandemic.
The WIV had a private database of viral genomes; but they took it offline in September 2019, they say due to hacking attempts. They haven't brought it back up, and the WHO has declined to ask for a copy.
SARS-CoV-2 certainly could be a naturally-evolved virus first transmitted from an animal to a non-scientist human. It could also be a naturally-evolved virus collected and accidentally released by the WIV, or a recombinant of multiple such viruses, or the descendant of such a virus after serial passaging. Nothing in Andersen's argument distinguishes any of these possibilities.
But don't trust me; check out Marc Lipsitch's Twitter feed today, or David Relman's article:
> Some have argued that a deliberate engineering scenario is unlikely because one would not have had the insight a priori to design the current pandemic virus (3). This argument fails to acknowledge the possibility that two or more as yet undisclosed ancestors (i.e., more proximal ancestors than RaTG13 and RmYN02) had already been discovered and were being studied in a laboratory—for example, one with the SARS-CoV-2 backbone and spike protein receptor-binding domain, and the other with the SARS-CoV-2 polybasic furin cleavage site. It would have been a logical next step to wonder about the properties of a recombinant virus and then create it in the laboratory.

This isn't a conspiracy theory, and it's not even a fringe viewpoint anymore. It's just a reasonable step in investigating the yet-unknown origin of what could be the worst industrial accident in human history.
So, except for the fact that you must believe WIV did all these experiments in total secrecy (so that nobody outside heard of it while visiting, etc) and now won't admit to having done them, it's not a conspiracy theory.
And again, RaTG13, the closest known relative of SARS-CoV-2, was sampled by the WIV in 2013 and published only post-pandemic. So it's unquestionable that they had at least one unpublished virus similar to SARS-CoV-2 in their collection; the only question is how many others.
It's likely that the only people who know the answer are under the physical control of the Chinese government. Even if they're sometimes briefly abroad, they likely have loved ones behind. So it doesn't take any voluntary conspiracy to keep them quiet, just a direction from a government that has amply demonstrated e.g. in Xinjiang its willingness and ability to punish anyone who discloses its secrets.
As I mentioned earlier, a proximal animal host would greatly increase my confidence that SARS-CoV-2 originated from natural zoonosis. Is there any evidence short of a direct admission from the WIV that would decrease yours?
Finally, Marc Lipsitch and David Relman are Harvard epidemiology and Stanford microbiology profs respectively. I'd rather people engaged seriously with the evidence than just relied on credentials; but are you saying they're conspiracy theorists too?
And you are making a claim about them lying, this comes unavoidably from saying that the VIW is the origin of SARS-CoV-2 as the VIW themselves are publicly claiming they have nothing closer than RaTG13.
