So... who decides what's fake news and what isn't? Is it based on what's accepted as true by society? What's accepted as true by the scientific community? Back in the day would a heliocentric view of the solar system be considered fake news? Who decides?

I think it's good that they aren't outright censoring medical 'fake news', but are pairing it with articles from 'actual professionals'. Ah, but who decides who's an 'expert'?
