The Supreme Court is set to consider a case on Wednesday that could have far-reaching implications for social media companies, involving the family of a Jordanian citizen killed in a 2017 terrorist attack in Istanbul. The case will decide whether social media companies can be held liable for aiding and abetting a specific act of international terrorism. The outcome of the case could have major implications for how social media companies moderate user content and could open the door to more lawsuits against tech companies for their role in the spread of extremist content.
