The Supreme Court announced this week that it will hear a pair of landmark cases that will determine the future of Section 230, weighing in on the Internet’s foundational law for the first time since it created the web as we know it a quarter-century ago. Lawmakers on both sides increasingly question Section 230’s protections, and a growing number of states have passed laws circumscribing it. Why has such a single section of a statute proved so controversial – and consequential? The answer lies in how the web has become increasingly centralized, with just a few companies crafting the rules that govern what people around the world are able to see and say online.
