These kids are very literally being left behind due to the covid lockdowns. They can't do online school because they can't get internet access. It's unbelievably tragic and heartbreaking.

One of my personal pet peeves with the FCC and the federal government's methods of subsidizing rural Internet, is that it's a horribly moribund process. The USF (universal service fund) was created a long time ago to put a tiny tax on every wireline dialtone phone service in the USA and apply it as a subsidy to last-mile copper phone operators mandated to serve very rural areas. Something like that could be applied to greatly increased rural broadband subsidies in general, which would benefit not just tribal areas but everywhere with a low density of people per square km.
Many of them are in medium sized cities surrounded by rural areas, or already in fairly sparsely populated areas colocated with long haul fiber ILAs and well positioned to serve very rural areas.
For instance there's one in Idaho that's adjacent to some intercity fiber (from where they're almost certainly buying a transport circuit to get to Seattle) which will have simultaneous visibility of satellites serving a vast area that has no WISPs and is presently dependent on consumer grade geostationary VSAT stuff.
The problem right now is sufficient density of satellites for seamless handover coverage to a CPE (make-before-break). Which would be the same problem if you were trying to serve a suburb of Seattle or a very rural area in Montana.
I rate it as highly unlikely that at the point in time when an ordinary consumer with a visa card can sign up for starlink service, they only offer it in major metro areas. The siting choices for the earth stations say otherwise.
Technological and economic limitations in Starlink, at least with the first/second generation of stuff mean that it's not competition for the sort of wireline services you can get in the suburb of a major metro area. If I were in Kirkland, WA and could get 500 to 1000 Mbps Comcast service, or gigabit GPON from Centurylink(Lumen), I'd certainly sign up for that before Starlink. You'd be looking at something that may top out at max speeds of 150-200Mbps down and 40-80 Mbps upstream (Starlink) vs a copper coaxial or fiber last mile setup that can do 800 down, and 300-600 Mbps up.
