- Keeping the Internet Neutral? « Federal Communications Law Journal – Tim Wu and Christopher S. Yoo discuss net neutrality. Yoo proposes an approach focused on network diversity, i.e. increased competition on the last mile, e.g. with several networks targeting market sub-segments. Competition is enabled by reduced barriers of entry into the market. In this framework, Yoo sees access tiering as a means to respond to increasingly heterogeneous user demands. Wu defends network neutrality, emphasizing the negative effects of blocking (e.g. VoIP) and access tiering (leading to Most Favored Nation scenarios) on innovation. Increased competition on the last mile is unlikely, as high barriers for market entry remain. Wu notes that Yoo has a top-down, he himself a bottom-up view of innovation.
