It was more too discount the fact that either of those things are conclusive evidence in some way. Idk where you're getting "slowly over decades" from because the entire story is barely 9 years old. All of the "journalism" on the subject is just people regurgitating stuff from Adrian Zenz, a dude claims he was "led by God to fight China" and works for a nonprofit that claims COVID-19 deaths and German WWII casualties count as victims of communism. Hardly a reliable source.
