Facebook, Twitter, Reddit and all social media has an incentive to leave this info up because it drives anger and it drives views and clicks. There is quite a bit of evidence these platforms literally are the cause of the anti-science rhetoric around the country.

I don't think that's true at all. IMO social media is just a symptom of the true cause.

The true cause is that most people are dummyheads, and that the propotion of dummyheads on the internet was far lower pre-smartphone era.
