They are now openly partnering with war industries and the government to assist them in doing things like bombing a school full of girls, killing hundreds in an entirely indefensible war of aggression.* This is a very dark red line to cross and despite Googlers being wealthy and privilaged, it is nonetheless a significant protest that deserves to be heard on its own terms. Ideally, a protest would change policy at the company.
Google management: Stop cooperating with the immoral and illegally operating War Department!
* I don't have evidence Google directly participated in the Minab school bombing, but this is the side they are supporting.
