This is exactly right. If FB, Twitter or HN apply their Terms of service rules selectively (or that the ToS are biased against specific political candidates or groups or opinions) -- then they are not a neutral platform. If they are not a neutral platform, these companies must not be able to claim protections reserved for neutral platforms (like this section 230). It is the same as a for-profit business must not claim same tax benefits as a Non-profit Charity. If they do, their execs will likely face jail time. Systemic violoaters, would face more jail time.
