" Claims that it was created by an individual, government, or country
Excluding claims that it was studied in, came from, or leaked from a lab without specifically calling it man-made"
So discussing possibility of a lab leak is not a problem, it's the deliberate bioweapon aspect that they're banning.
"The goal of this policy is to remove common viral hoaxes that have been repeatedly debunked by independent fact-checkers."
The editor's note says there is no evidence that this is the case. There is no strong evidence about anything regarding what are the origins of the virus. But it's still entirely within the realm of possibility that it could be true.
Sure, things aren't black and white and I never said they were. But Facebook will ban you for suggesting that it's possible that the virus is man-made, right? So they're the 'extremists' here.
How are these Fact Checkers to decide on a complicated and political question like a Wuhan lab leak hypothesis? They have a claim to truth, based on what credentials or mechanisms, that the rest of us don't have access to?
