Longmont, CO has had municipal fiber since 2013. In 2005 the state passed a cable industry-sponsored bill requiring all municipalities to pass a ballot measure before they could build municipal broadband over 256kbps. Longmont had such a measure in 2009 and it failed due to campaigning by private ISPs. It passed later, and in the years since the speed cap has been removed. But yeah, it was a fight against private industry to use infrastructure _built and owned by the city_ for its only possible use.
