Oh FFS - fixing this is EASY
Step 1 - Setup a news white-list. If you aren't on the list then your "news" won't be allowed.
Step 2 - Create a process whereby *any* news site can apply to be added to the white-list. This would be human reviewed by qualified people and the sites would be required to meet very basic journalism standards such as only publishing actual, factual news and having a clear demarcation between what's news and what's commentary or editorial content. (This is neither difficult nor burdensome.)
Step 3 - Review these sites on a regular basis to make sure that they are still in compliance.
