The bright and shining difference is that a CDN does not have a contract with the end user, and consequently doesn't connect directly to them. When we talk about a "fast lane" (or more accurately a "slow lane"), what we essentially mean is an ISP holding access to its users hostage. This is the opposite of how a CDN works, because those are paid by the provider to speed up access to its data, rather than being paid by the consumer for access to the provider's data. Basically, what is proposed here is preventing an ISP (which is already a recognizable category) from starting a CDN business — a very bad one, since it only delivers content to itself — and artificially slowing down non-CDN traffic that has already been paid for on the other end in order to prop up its CDN business.
