I find it a bit amusing that someone on this site, where so much of the content is about optimization and business models, is acting so morally offended by the concept of price differentiation.
So many of the articles are about business model optimization because it's not the primary nature of hackers - they need to be reminded. The major difference is that the businesses here are new and the market and product are uncertain (inherently complex); Internet access, by definition, is a solved commodity.
Really, it is? How come in 2012, I, who live in decent sized US city (Metro area is about 140k), still pay about $40 for 10Mbit connectivity, barely better than I could get 10 years ago?
Because utilities tend to plateau when they provide "enough" capacity? The house I'm in has the original water main and electrical service from 1900 and 1940. Being a commodity says nothing of the price (/trend), just the fungibility.
