Actually all of his claims are facts unless proven otherwise. Do you have proof that these facts (Wuhan playing with these viruses, funding etc) are not true or you would like them to not be true?
I linked a thorough thread from a domain expert explaining in detail why the claims are false. These things have been addressed/debunked many, many times but still get repeated because the untruths get amplified and the rebuttals not.
I am not being vague, I literally posted a link to a rebuttal thread.
This is why I don't post on hacker news any more.
