Unlike Ondemand or pay per view pricing is not based on a per viewing or a predefined rental period. All content decisions are made by Comcast versus Ondemand where the content providers control what content is available and when it is available. For example HBO makes different content available via ondemand each month and the decision regarding which content is available is made by HBO and not Comcast.
It is like and intended to compete with Netflix and other Internet streaming services. It operates differently from traditional pay per view and content streaming services. It also is not like a traditional premium tv channel for which a monthly fee is paid. It is exactly this type of service the agreement was designed to prevent favorable treatment of versus the same type of service provided by someone besides Comcast.
I hope they legislate a more pure neutrality, but I can see how what you are saying allows them to continue this.
So is pay per view. Rephrase your argument in such a way that pay per view is allowed and this isn't. You can't, because your argument is incorrect.
Pay per view is allowed, and so is this.
