I always thought the use case for WISPs was for places that have at best the fiber line built for "a cell tower" but are otherwise cut off from more solid ISPs who want home internet or for places that are best have shitty ADSL. That of course means people in distant nowhere. I never thought of WISPs existing elsewhere as it doesn't make nearly as much sense if you have access to "real" broadband. I suppose this niche was wider at one point?
