Are you sure about those numbers? That's massively expensive, and it's hard to imagine ever even being profitable. If you charged your users 60 dollars a month at a minimum for access to that line you'd still need a minimum of 33 people, for one area. At just the rates you describes. Let alone the 33 cents per foot for the cable lines going to peoples houses and additional expenditures.

How on earth is the internet even possible at these rates?

Googles charging people 70 a month of gigabit up and down, those are sparsely connected homes throughout Kansas. The monthly maintenance cost alone for one block must be enormous, and for what? Two or three homes each block?

I was willing to accept that they were losing money on this endeavor, but not as catastrophically as this!
