Ukraine

That is what Musk said. Which is arguably pretty biased source. It was also said after the book was published, which makes me think Musk either didn't even read his own book and no one in his team did see a problem with what was in the book. Or he didn't even see it as a problem himself which wouldn't be his first catastrophic failure to read the room.

if you think it should not have been disabled there in the first place then that would mean Russia could use it for their own drone strikes aswell

Drone strikes on all the battleships Ukraine has? Or how exactly would they use it in waters where Ukraine only visits with drones and missiles?

Also I don't think it shouldn't have been disabled. I think it does not matter if it was disabled. The only difference it made was that Musk was in position to turn it on rather than to not turn it off. And he chose to help russian terrorists fucking up Ukraine big time as russia got its hands onto the undamaged drones.

If I had agreed to the request, then SpaceX would be explicitly complicit in a major act of war and conflict escalation

Sounds like what russian asset would say. Perhaps not because he's forced or bribed by russia, perhaps it just makes business sense.

In my view that is a perfectly valid reason

That's your opinion. I don't think it's valid reason to help terrorists. Those ships were later used in attempt to block food export risking famine in certain parts of the world and to lob missiles at Ukrainian cities. They were also used for that before. Perfectly valid reason to call Musk an russian asset IMO.
