Elon Musk's fight defending X's content moderation decisions isn't just with hate speech researchers and advertisers. He has also long been battling regulators, and this week, he seemed positioned to secure a potentially big win in California, where he's hoping to permanently block a law that he claims unconstitutionally forces his platform to justify its judgment calls.

At a hearing Wednesday, three judges in the 9th US Circuit Court of Appeals seemed inclined to agree with Musk that a California law requiring disclosures from social media companies that clearly explain their content moderation choices likely violates the First Amendment.

Passed in 2022, AB-587 forces platforms like X to submit a "terms of service report" detailing how they moderate several categories of controversial content. Those categories include hate speech or racism, extremism or radicalization, disinformation or misinformation, harassment, and foreign political interference, which X's lawyer, Joel Kurtzberg, told judges yesterday "are the most controversial categories of so-called awful but lawful speech."
