Dare we inquire how long you have lived. :)
But seriously, I am not sure that the scientific community, nor all national governments, have reached a clear consensus on gain of function research. It is still a developing issue. Welcome to be corrected on that. Such research could potentially help to prevent pandemics as well as accidentally start them. The idea that scientists in the US might have been working with scientists in other countries, including China, on GoF research is not shocking to me. Here is a paper from 2016 on the ethics of GoF research:

Perhaps the old saying about mistakingly attributing malice to incompetence applies here.
As for the cover-up, it is difficult to imagine that David Baltimore is wrong. I used a textbook he co-authored when I was in school; he is one of the pioneers of the biotech industry. It seems unlikely this was not created in a lab. Then again, it is probably easier to prove someone in a lab made a mistake than to prove soemthing exists in nature.
