I'm fascinated by the economics of running fiber. A neighboring company from a few counties away has brought in a fiber backbone into the county. This was run via aerial fiber, they were pretty clear their objective was to hook up schools, government and businesses once in the county. After that then focus on residential. Our county is pretty rural, the largest town 5k people. The backbone ran past my parents house which is very rural farming area. I kept telling them they wouldn't be able to get internet by tapping into a point to point run. Apparently I was wrong the company sold them 100mb down for $80/m with a $700 install fee. They are tapping thier backbone at each house and coming off of the tap with a smaller fiber directly into the house.

My condolences running a wisp as well. I know some of the guys at our local wisp, they sell a lot of subscriptions but they really don't have the capacity to keep selling service. Really poor quality connections along with things the OP mentioned like interference and equipment issues.
