No one else is even close to being able to offer 100/20M rural service.
In my parents county (very rural), the local electric coop is running fiber on all their poles. Its possible that my parents living 10 miles from the nearest town (2 4-way stops, a grocery store and a couple of gas stations) will get gigabit fiber before my friends that live in a well off suburb in a dense urban area will.
It's nice that your parents have a co-op that is actively rolling out such infrastructure. That's not the rule though, and the U.S. has massive swaths of low density population areas with substandard internet speeds.
