Why are so many getting better medical advice from random people online than their medical professional?

I've been posting about hydroxychloroquine on a local community-oriented social media site since not long after Trump mentioned it. At first I got a lot of push-back. People telling me to STFU and stop pushing false hope, that kind of thing. But as people actually started to look at the evidence I've posted and realize I was correct, they're basically asking that exact question. This is the biggest red pill of all time.
