Starlink has been supporting Russia over Ukraine (congressional investigation into this). So I would bet against Russia, but you never know. Could be rouge. Anonymous has promised in the past to mess with Musk... could be that. Well funded and some crazy good hackers.
In terms of actual actions, Starlink has done a lot more for Ukraine than almost anyone else, since early on. Musk says stuff from time to time in order to try to keep Putin from noticing this, and pushing him out of a window or something. But his actions are that he let Ukraine use Starlink for over a year for free, and they still use it widely today.
No one is using Starlink for free. Poland has been paying for all of those "free" terminals DoD was sending over. Currently Poland is still paying for more than half of all Starlink in Ukraine.
