Net neutrality is a basic, but notoriously squishy, principle. It means that a broadband internet provider should not block, slow, or otherwise unfairly discriminate against any websites or online services. Despite being a simple idea, net neutrality has proven difficult to translate into U.S. policy. It sits uncomfortably at the intersection of highly technical internet architecture and equally complex principles of administrative law. Even the term “net neutrality” was coined not by an engineer but by a legal academic, in 2003.
