It's totally reasonable. My position is that I think network operators and owners should be able to do that they want. I was just pointing out that virtually any time a network operator or owner wants to control the traffic in their network a certain crowd comes out of the woodwork and decries abuse by bad actors.
Size and scope matters. Large network operators that have a de facto monopoly on Internet access in many places should absolutely not be able to do what they want, but this is a function of their market power, not something inherent to any network operator.
