There were two schools of thought on COVID early on last year on its origin: WET market and the virus research lab in WUHAN. In the beginning, anyone who brought up the lab was shamed and probably blacklisted.

Some of the kinder stories about the lab involved improper waste handling which is a very realistic scenario. I think a town in Russia suffered an outbreak of Ebola because of cleanliness standards, but don't quote me on it. I know it happened, but I'm not exactly sure why.
