I don't think it's a good precedence to make companies liable for the posts of users. I do think it's reasonable to examine the ways Google and Facebook profit off of extremist views and surface extremist views algorithmically. As soon as Google and Facebook moved to having an opinionated queue of content (Youtube's suggested videos and Facebooks timeline) based on things like engagement, I could see the argument made that they have both ceased being mere conduits of information and became publishers themselves.
