If there is a conspiracy in terms of lab leak, etc. it goes far further than Wuhan. I read some papers in the early days of the pandemic related to things like this type of coronavirus and monoclonal antibodies and related which got yanked from the internet soon after, possibly just to prevent a witch hunt, which were a bit of a smoking gun.
Even today though there are a lot of holes in any of the possible theories - for a natural origin we are missing 3-4 decades of intermediate developments which is improbable though not impossible have been missed entirely, there are a lot of hurdles to intentional design but that doesn't rule out either someone individually making a breakthrough or having insight which isn't widely known or even incompetence that happened to produce a viable outcome just by chance, etc.
