The city of Ammon in Idaho is now offering internet access for free. Early this week, its mayor Sean Coletti proudly announced on Twitter that residents could get a no-contract, no data-cap internet service offering 15Mbps for just $1.88 a month. That was offered by one of three companies riding on top of a fiber network that the US city is paying for through municipal bonds and Coletti flagged it as a great example of what real competition can do in the internet market.
