On the media 'not taking it seriously' - because there was no evidence whatsoever outside of conjecture and it was being pushed heavily by misinfo merchants. No grand conspiracy. Skepticism is a good default approach to take for info heavily pushed by such sources with no solid evidence.
There were tons of articles and threads on it everywhere including HN, no one was being silenced, give me a break. The oppression complex is really out of control, as if people were being visited by the secret police and forced to immediately cease all discussion about the lab leak theory. It just had no credibility due to lack of evidence. As more info comes to light it's being given more credence, simple as that.
Really seems many want to feel like they've been oppressed and silenced when that couldn't be further from reality, reaching absurd levels of delusion here.
What is absolutely terrible is for the media and big tech to ACT like they are the absolute authority in any field they have interest in. We're heading towards "ministry of truth" levels of censorship.
