Even if the giants were broken up you'd still have the problem of local monopolies. To actually enable competition within the same market you'd probably need to go the route of a regulated utility that is required to lease their cable lines to independent ISPs, as we've done with phone companies. Only then could the market even conceivably let consumers choose between tiered and neutral services. Even then it wouldn't necessarily be good in the long run, because consumers will prefer the cheaper (tiered) service, not "realizing" the long-term effect that would have on inhibiting startups and competition among internet services.
