CompuServe was in many ways its own single-source proprietary internet. And CDNs are by nature distributed, even if their ownership is not. Just as it's unreasonable to expect a site operator to maintain their own global network backbone, it's unreasonable for every site to deploy global infrastructure for efficient content delivery. Which is not to say that we wouldn't be better off with a more diverse and distributed-in-the-ownership-sense market of CDN providers.
