The ISP model is hard because it just requires fucking shit tons of money to solve, and there's no getting around the tragedy of the commons problem. With telecom infrastructure, you can either use wired (expensive and with a heavily fragmented regulatory environment) or wireless (expensive with extremely limited spectrum - see the $12+ billion spectrum auction happening now).

Disruption is well and good, but it requires new technology that delivers similar services for a fraction of the cost. Until someone figures out a way to bring the economics of delivering content to end users down by a factor of several hundred, we're stuck with the current ISP situation.
