Laying fibre is really expensive - in really rural areas it could be $100k+ per subscriber, so you will never see a return on investment for doing that
And yet, a local company in my state just ran fiber to 5000 homes in my area for what I told was 1 million. They used directional drilling, it was cheap and easy. Then all the sudden my local phone and cable company “also” put in fiber.
So while I’m in a suburb, I know for a fact these guys are all over the state and growing, including rural (and so is the local telco/cableco). I challenge that 100k number, that’s bullshit telco numbers. The word is unprofitable, it is unprofitable to run fiber when you are the only competitor.
