Google is a private company that can choose how to make money. If it chooses to not show advertising on any particular category of site, that's a commercial decision. If its shareholders or customers are upset they can unseat the board or find another provider respectively (as you wish to do). A competitor may even see a commercial opportunity and make a business model based off carrying ads on fake news sites-Google doesn't do ads on porn sites, and yet those sites seem to be doing OK on ad revenue.
