"If there's not enough demand..." Demand is not that simple. There could be tons of latent demand and the internet seems to be one of those things that seems to show induced demand as well. People are incredibly adaptive and may be working around the problem of crappy internet one way or another. If there was just straight up "demand", these near-monopoly ISPs form a market of "you can't vote for whoever you want as long as I get to choose the candidate" type systems. That does not a healthy market make and supply/demand do not work out like it does in econ 101 textbooks in unhealthy markets.
