> Big Social Media firms have to make decisions on speech.

The fiction underlying their section 230 liability shield is that they don’t have to make those decisions. They’re just “dumb pipes” for user generated content. The Supreme Court punted on this issue in Twitter v. Taamneh but it’s going to get resolved eventually.

This is a common but backwards misconception. Section 230 was written to ensure that online platforms could make decisions on speech and did not have to just be dumb pipes. Congress was worried that a "dumb pipe only" regulatory regime was taking shape through court decisions, which would have forced platforms to choose between letting users post obscene rants and accepting liability for anything defamatory users might say.
