You don't need access to a proprietary database to refute that sars-cov-2 wasn't copy-pasted at these restriction sites. We have public sequences of the closely related coronavirus strains. The unnatural SNP pattern would be absolutely obvious if someone patched together different lineages around these specific conserved RE sites. Instead we see a set of conserved RE sites related across the publicly known strains by homologous recombination.
What I've tried repeatedly to impress upon people here is that most routine cloning strategies leave pretty clear signatures, and the idea that a lab would go so far as to eliminate these signatures for such mundane virology work is tantamount to a much more elaborate conspiracy theory.
Your assessment relies on two assumptions. The first being that samples from the “public sequences” are identical to the sequences China’s labs purposefully unpublished early in the pandemic. The second being the assumption there was no nefarious purpose to the well-documented gain of function research taking place in Wuhan.
I don’t need to be a biologist to call your assumptions out as junk science.
