Why should they. They are in business to make money, and cannot effectively self-police. Imagine a time, way back after WWII when fascism almost took over Europe and destroyed democracy, when the grown-ups in charge took responsibility for fighting against intolerance and propaganda by carefully regulating communication through a government agency. For better and sometimes worse, but mostly better, this agency created LAWS that prevented the distribution of propaganda and obviously false and unbalanced news through regulation of the broadcast media, specific rules about what could be considered 'news', and the fairness doctrine. These grownups cleverly called the agency the Federal Communications Commission, whose job was not restricted to just the airwaves: it was to protect the people from hate groups, harmful extremist content, yes communist propaganda, and many other unbalanced or biased sources of information.
