Unfortunately, the article states explicitly that there was ill intent and extensive PLA involvement with the lab.
The military was also given positions of responsibility in the Wuhan institute, according to a US Senate report. A book published in 2015 by the military academy discusses how Sars viruses represent a “new era of genetic weapons” that can be “artificially manipulated into an emerging human disease virus, then weaponised and unleashed”.
The authors are PLA researchers, and one of the book’s editors has collaborated on numerous scientific papers with Wuhan scientists. They discuss how Sars can be weaponised by fusing it with other viruses and “serial passaging” the resulting mutant to make it more dangerous.
The investigators believe the Chinese military had taken an interest in developing a vaccine for the viruses so they could be used as potential bioweapons. If a country could inoculate its population against its own secret virus, it might have a weapon to shift the balance of world power.
