I always thought the social media companies' effort to censor fake news was a mistake. I just assumed it would take some time to catch up to them. Instead, as soon as they started censoring things they thought were false they immediately got a huge consequential issue of global importance completely wrong. I was once in a meeting where we were being told about a product that was basically going to be a clone of Teachers Pay Teachers (but they'd be paying us instead). In Teachers Pay Teachers teachers upload lesson plans and what not and other teachers buy those plans. The idea was now teachers could upload to our service and teachers could buy from us. I asked how we could tell the quality of the content that was uploaded. How could we tell people weren't uploading bad materials? It was clear the people designing the project had never thought about this problem for a second and they had no solution. To me, it seems similar to what's happening here. Facebook et al naively assumes they can differentiate fake news from real despite having no capacity to do so. "We'll just remove stuff that's false" is the same kind of mistake as "We'll just post stuff that's true." Do you know what's true?
