My Internet connection contract already says that they reserve right to: Queue, Prioritize and Throttle traffic. This is used to optimize traffic. - Doesn't sound too neutral to me? It's also clearly stated that some traffic on the network get absolute priority over secondary classes. Interestingly at one point 100 Mbit/s connection wasn't nearly fast enough to play almost any content from YouTube. - Maybe there's some kind of relation, maybe not.
