It looks like the waitlist is around populated areas. If you zoom in you can often see that urban areas are waitlisted while anywhere remote or without much housing is available.
I got off the waitlist and live in the bay area -- possibly im not doing something right or Starlink is extremely spotty; it gets "offline" most of the time and very rarely gets online so I can actually use it. After 4 months of unuse I canceled my the $99/mo subscription which is more than the internet I actually pay for
