I think the poster is referring to the 'ltehacks' forum/website, which is a group of people using things like 700/800/850/1800/1900 band LTE last mile, via things like cradlepoints and hotspot devices, where no WISP exists.

Because they can achieve much better latency and GB/month through that than by buying a wildblue type terrible consumer grade VSAT.

Starlink will be revolutionary for those people who live in a place where no viable fixed-wireless WISP exists.
