So, in the case of Starlink, they absolutely CAN provision customers like that, and that's EXACTLY how it works right now - invites happen per "cell," and each "cell" has a capacity quota.
Recently, they've been overprovisioning "cells" for some reason or another, and the service has slowed down, so it objectively didn't meet the thresholds and they'll need to bid again. This also seems reasonable.
I say this all as a happy Starlink customer - negative externalities to space junk and obnoxious fanbase aside, it's way better than my previous fixed point to point WISP experience was, and worlds better than ADSL stretched to the bitter end of distance capability over lines from the 1970s was.
