I've read that before and I've discussed it with a lawyer (among other related articles & topics). He rolled his eyes at much of it, but he also rolled his eyes at the "platform vs publisher" distinction that so many naive people make. Still, he agrees that social media companies are tickling the dragon's tail when it comes to Section 230 protection.

Before you dismiss my anecdote as one mistaken lawyer, note that the chairman of the FCC (who is a lawyer) and Justice Clarence Thomas both think that Section 230 doesn't offer nearly as much protection as social media companies seem to think it does. In response to recent events, the FCC plans to issue statements clarifying the meaning of Section 230.[1]

That was a very good read. Thanks for linking that!
