- 4chan saw the pandemic coming in January 2020, and predicted it would be big
- 4chan knew it wasn't 'just another flu' in March 2020, when the media was downplaying it
- 4chan figured out the virus is transmitted via areosol, not just particulate
- 4chan worked out that Vitamin D can help (even Fauci admitted he takes it)
- Wuhan Lab hypothesis
That's just off the top of my head. Sure, 4chan got a lot wrong: but better to get all the (possible) facts, and sift through them. That's science. What are you going to do otherwise? Trust Fauci?
4chan isn't know for enormous deference to anyone, so the fact that "they" (collectivizing 4chan always irriates me, but whatever) got things right given the head-in-sand public attitude (*) of the administration isn't really surprising.
(*) Trump of course privately told Woodward that it was really bad.
