The change process doesn't exist at all if the services that are offered by a company are entirely private, except by customer choice. And if there are too few choices, then well a monopoly ISP could ban encryption on all their offered links, and parse all the data going by for resale to marketers and right back to the government too - except perhaps for those inconvenient government privacy regulations (or other regulatory rules) which may stand in the way.
The issues are nearly entirely orthogonal. Network neutrality was pretty irrelevant to them installing boxes to spy on all our communications. It was irrelevant to using that data to decide whom is a communi... err terrorist. It will be irrelevant to when they decide to use that same data to limit your freedom.
Ahh, but we accept the unbounded authority of law to dictate far more than our internet: our property, our freedom, and (unfortunately) our very lives. What reason is there to expect the government not to regulate every other aspect of life with data from the internet? At least Comcast can't do that.
