But then the thing I am relatively unsure about the stance of net-neutrality proponents would be whether it is legal for Comcast to sell "shitty internet." That is something that always get throttled first, that blocks certain websites, or that prioritize promoted services. I mean a VPN could legally do that, and in the case of a ISP my personal idea of net-neutrality would be that a neutral service needs to be available and that non-neutral offerings needs to be clearly marketed as such. I honestly see this as a possible drive to competition, as ISP would be forced to disclose how shitty or not the service is.
