How should Starlink know if Russians or Ukrainians use it in the war zone?
Suppose Starlink would even more aggressively constrain access to "known ukrainian-dominated territory". A possible error would be that an Ukrainian soldier suddenly loses access since a few 50 meters apart Russians captured an Starlink terminal. The news would be even worse in the public opinion in that scenario.
In general it is always better to assume well-intent instead of resorting to reflexive "x is bad" arguments, which was my take of the GP.
