> The ask of companies under section 230 is that they be allowed to publish
No. "publish" is a distortion promoted by people trying to use the repeal of Section 230 as a weapon. To the extent liability should exist for speech at all, companies should absolutely be liable for what they publish. They should not be liable for what their users publish. Without that distinction, the Internet cannot exist as a medium for any kind of user-generated content. Centralized services providing curated content would fare just fine, but anything that allows users to interact or contribute would die.
> The question is, what do we get back for allowing them that privilege?
A functional Internet. Websites that contains content supplied by others, that aren't "anything goes" cesspools. An Internet that helps people interact in a read-write manner, not just consume content in a read-only manner.
