And now every house has 10Gbps with free choice of operator.
Normally what most communities do is wait for one of the big fibre operators to reach them and start digging. But these locals did all the practical stuff like digging, laying fibre and building the actual grid themselves by hiring their own contractors.
Larger communities, towns and cities, usually have a city wide fibre grid managed perhaps by the local energy company or by the municipality. They in turn might out-source the fibre digging but they still manage the grid and determine what operators are offered to the citizens.
In big cities (we have three of those) you can find multiple city wide fibre grids. One managed by the municipality/city and some y large property owners that take it upon themselves to equip their buildings with fibre.
Regarding the wireless setups in the article I am very skeptical because this was a trend 10 years back in Sweden and a lot of people lost money by investing in it when they could have just waited a few years and had real fibre.
But the US is special because of its size. So wireless might be all they can get for many years.
