That's obviously not true. Ethics often have some nuance and some subjectiveness, but it's not something entirely subjective up to "politics".
Saying this makes it sound like you work at a startup for an AI powered armed drone, and your view of it is 'eh, ethics is subjective, this is fine' when asked how do you feel about responsibility and AI killing people.
Is it always wrong to kill people? If you say yes, then you are also saying it's wrong to defend yourself from people who are trying to kill you.
This is what I mean by subjective.
And then since Google is beholden to US laws, if the US government suddenly decides that helping Ukraine to defend itself is wrong, but you personally believe defending Ukraine is right, suddenly you have a problem...
