I think there's a very reasonable distinction here between platforms that publish content without promoting it, and what Facebook is in the business of doing which is promoting content. Facebook opens itself to additional liability by increasing the reach of posts which do well. In practical terms I see the basic issue as being a lack of downvotes. Users can do nothing to combat disinformation, because every form of engagement boosts posts.
