That said, I'm pretty confident municipal internet is bad thing in the long run (compared to actually competitive markets, not local monopolies)
Problems:
(1) Unlike say, water, sewage, power - internet tech changes 10gig might seem fast today. In 15 years it will seem slow. Will the government upgrade? My guess is they'll be slow to upgrade where as places with truly competitive markets will upgrade quick. I watched this happen in Japan. There were 4-5 different providers. One upgraded (twice the speed of competitors for same price), Competitors were forced to upgrade or lose their business
(2) Government run internet is bound to eventually be lobbied to be safe (what do you mean my taxes are being spent so people can download adult content! Stop that! ... etc)
(3) With Government run internet there is no competition so no one else can enter the market and compete.
Come back to this comment and in 10 years. See what speed competitive markets are at and compare to municipal and non-competitive markets.
