Example of how well the laws work
Some of the late 80's/early 90's legislation opened the doors to having more than one provider in an area, e.g. if Comcast was the incumbent cable company then someone else could come along and build out a cable network and compete with Comcast (or VZ, or Cox, or AT&T, or SBC, etc).
This, in theory, was a great idea
In practice it had major issues because while the FCC let it happen at a national level, it could fail at a local level (but not always)
A company I know of tried to get permission to build out a competing network in Baltimore, MD. Despite multiple submissions to the city leaders, the decision got repeatedly delayed. And delayed. And delayed more. They were never explicitly told "no" from what I understand, but they were never told "yes" either. Why? The Comcast head office at the time was literally *across the street* from the city offices.
End result? Baltimore never got competing services.
There are other stories I've heard too about local interference for petty political reasons, ultimately to the detriment of consumers. Such as the incumbent cableco in another area didn't have an obligation to provide service to the entire county, but when a competing provider applied to build out service they were told they had to run cable to every property in the county. Fair? Don't think so.
Light regulation only works when everyone plays nicely together and has equally big bank accounts. When one provider is significantly bigger than another, regulation is needed to stop the big guy squishing the little guy like a bug on a window of a high speed train.
The last mile providers think they own the eyeballs and that since there tends to be no effective local competition they can do what they like to protect the revenue/profit stream they've set up. They need to be shown the error of their ways.
