Is it reasonable to be able to extract any revenue from Ukraine during a war? If not, then there is no loss of revenue. There is also no increased operational costs - the constellation is up there already, and replacements need to be sent up from time to time, regardless of whether they fly over Ukraine or not and regardless of whether they keep their radios on while doing so. The operating cost of a satellite constellation cannot be split by country served and stopping service to one country does not change the overall cost.

They may stop sending dishes though, but, apart from that, not much would change.
