This paper seems credible, and there is a lot of other evidence showing that the CCP/PLA was doing genetic modification on coronaviri. So if we assume that the paper is correct, we must next consider whether or not the SARS-Cov2 virus was accidentally or deliberately released. If the release was accidental, the PRC has taken extreme measures to create disinformation and hide the truth. They didn't do that the last time they had a similar accident. If I go any further with this line of reasoning, others will likely call me a conspiracy theorist, so I will stop now.
