The Supreme Court has chosen to tackle a question at the heart of the debate over Big Tech. When they decide Gonzales v. Google, the justices will have to address for the first time the extent of the legal immunity granted to internet platforms such as YouTube (owned by Google), Facebook, and Twitter under Section 230 of the federal Communications Decency Act. Many conservatives are among those hoping the court will curtail this immunity. But they are likely to be disappointed by a post-230 world.
