So this is an interesting story. At some point researchers from the WIV requested some early SARS-CoV-2 sequence information to be removed from the usual databases, maintained in the USA. This was done, although a paper trail remained, and those sequences have now been recovered.
Source is Nature, so this should be considered reliable and in the open now:
It is not yet clear what this means, and without seeing where these sequences land on the phylogeny map, it isn't even clear that doing this would confer any advantage. But it doesn't make sense. This would have required cooperation from colleagues in the USA, though it would not be particularly difficult to pull off.
Speculatively, this could be evidence of an attempt to firm up the Huanan Seafood Wholesale Market as the preferred origin story. The article suggests that the deleted sequences show an early divergence from those samples that would conflict with that story, and perhaps that is why they were removed. I can think of some less nefarious purposes, but I think we need to get a better answer. There's really no good reason to do this.
