This entire article is already engaging in political and ideological battle - René Mayrhofer is explicitly saying that he's unwilling to work at Google because he has a political problem with some of the decisions Google is making, namely abandoning earlier stated carbon-neutrality goals and being willing to make deals with the US military.
My contention is that if he considers this to constitute Google losing its moral compass but not the James Damore incident, which happened the same year he started working at Google; then there's no particular reason to think that his notion of a "moral compass" is any different from object-level agreement or disagreement (or simply not caring), about any particular decision that Google makes. Someone similar to Mayrhofer might well be willing to work for Google because they make a different judgement than he does about the political importance of AI model energy usage; and throwing terms like "moral compass" around is exactly equivalent to having an object-level disagreement about a political issue.
