which indicates that something like 98% of American broadband is either over cable (throttleable at will by the cable owner to discourage competition) or telco (throttleable at will by the telco to discourage competition).
I'm PAYING for my bandwidth, it's not a gift from the pipeline owner to me, to Google, to Vonage or anyone else. I'm entitled to use that bandwidth for any legal purpose, particularly if I'm using it for a service (VOIP) which competes with other business lines of the pipeline owner.
Wonderful, but none of that supports your original assertion that the providers have a monopoly. You even admit that there is no monopoly. I am assuming monopoly was the (poor) excuse you were using to justify government interference in the market.
Your new argument falls apart logically. You pay for cable television as well, but you are limited to the programming offered. You have no ability (or right) to specify what or how the provider delivers programming. The networks practice discrimination in their programming. Are you proposing a "broadcast neutrality" law that forces television networks to provide equal access for every fool with an idea?
The fact is that you have bought the socialist argument for "fairness," something that doesn't actually exist. You seem to believe you have some "right" to internet access. You favor socialism if it suits your desires.
