So 230 is well intentioned, and without something similar we wouldn't have some of the nice platforms we do have.

Not true. These platforms could exist where you self-publish and they amplify it - like what cloudfare does for thedonald.win - so that you don't need a terabit internet connection.

They don't do this because 230 let's them get away with hosting your content instead of amplifying it, and that lets them censor and monopolize your content.
