I feel like you've been missing a lot of the discussions lately on the web, a lot of large ISPs have made no compete contracts from towns and cities and even go as far to block municiple internet (citing unfair competition) when the citizens vote for it because it will be cheaper. The problem with these contracts is that no other ISP can come in and comcast/time warner have actually had to let a few of these contracts go to appear not to be a monopoly in their merger persuit.
