I'd like to hire you for "just a job". I'm gonna make a big deal about how my company is "morally good" and "does no evil". Hitman OK? No? How about I hire you for janitorial duties at first, and slowly transition you to the death squad duties over 10 years? Don't quit, it's "just a job".
Given that, at Google, he only went from a Network Engineer [2005] to SRE [2020], I don't think you can call that moving to defense contracting, especially as a SRE for the Ad Serving platform.
I think you are reading way too much into my satirical critique about the terrible "just a job" mindset (avoiding the obvious "I was just doing my job carrying out the Holocaust" analogy), which as a generally independent critique can stand on its own legs without needing to be specifically applied to the current scenario at hand.
To really clarify this, I made the exemplary initial job "janitorial duties".
