Why did you say “anything
else”? This isn’t a conspiracy theory. They only detail that is even in question is whether or not one of their samples leaked. Nothing else about what that lab is, or what that lab does, is even in question. They go 1000 miles away to get bats and bat poop and bring it to the WIV to study bat coronaviruses and they modify them to be more transmissible. This is basic virology in 2021 and they have been proudly telling the world that they do this for years. None of that is speculation.
The question of whether one of their viruses leaked out again (yes, again!) that was a bat coronavirus found right by the bat coronavirus lab, or whether it was a remarkable cascade of coincidences that still has no viable complete hypothesis (the “modified” virus doesn’t infect bats anymore), is not one of “conspiracy”.
