Supreme Court rules for social media giants in cases over third-party content, declines to address Section 230

The Supreme Court on Thursday handed big tech companies, including Google and Twitter, legal wins in a pair of lawsuits alleging that the companies should be liable for ISIS attacks because of content the terror organization promoted using their platforms.

The companies were sued separately by the families of the victims. In the case against Twitter, Justice Clarence Thomas authored a unanimous opinion saying that the families did not provide sufficient evidence to establish that the companies should be held liable for aiding and abetting.

"Defendants allegedly knew that ISIS was using their platforms but failed to stop it from doing so," the ruling states. "Plaintiffs accordingly seek to hold Facebook, Twitter, and Google liable for the terrorist attack that allegedly injured them. We conclude, however, that plaintiffs’ allegations are insufficient to establish that these defendants aided and abetted ISIS in carrying out the relevant attack."
