There is currently no tech company exception to California civil rights laws, of course. Any social media company that directly engages in violations is as liable as any individual or any other sort of company would be.
But that's not what S.B. 771 is about. California lawmakers aren't merely seeking to close some weird loophole that lets social media platforms engage in threats and harassment.
No, they are trying to hold platforms responsible for the speech of their usersâ€â€in direct contradiction of Section 230 of the federal Communications Decency Act (CDA) and of Supreme Court precedent when it comes to this sort of thing.
