Perhaps Zuckerberg has been given a talking to, about the ramifications of "misinformation policing" with respect to Section 230 of the Communications Decency Act of 1996:
Section 230 is a part of the Communications Decency Act of 1996, which itself is a part of the Telecommunications Act of 1996. The Communications Decency Act was an attempt to protect children by regulating pornography and obscenity on the Internet, among other things. While the provisions regarding obscenity on the Internet were struck down by the Supreme Courts decision in Reno v. ACLU, Section 230 has stuck, and remains in place to this day.Exercise too much control over what gets posted on Facebook, and, at some point, Facebook might face being considered less of a "provider internet services", and more of a "publisher", and become liable for what gets published on their platform.The key part of Section 230 is as follows: No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider. What that means is that service providers arent liable for the things their users say. If someone defamed me on Twitter, thanks to Section 230, I cant sue Twitter over what was said, because of the safe harbor created by the law.
Why is Section 230 important? It helps promote free speech on the internet. As the law stands right now, service providers cant get sued for what their users say, so they have no incentive to try to limit the speech of their users. However, if the protections provided by Section 230 were not in place, then ISPs, social networks and other places where people can speak their mind on the internet would need to police what their users were saying in order to attempt to minimize the possibility of ,getting sued.
It is Zuckerberg's financial assets on the line if that happens, not the board members, and I could see him getting nervous about the possibility of a Trump-appointed judge hearing the case.
Goodbye section 230 protections --> goodbye Twitter.
