At this point I assume anyone with more than five years at Google is morally bankrupt to at least some degree. I don't want to paint them as bad people or anything but can't find better words for it - it's so obvious that if you stick around, you are accepting it and likely contributing to some degree. People I still talk to are generally honest about accepting it. I wonder if they will all reneg with this sort of quitting post when the time comes.
I think you're coming from a privileged position - finding a job is extremely hard*, and if someone stayed somewhere that paid well then it's a bit extreme to say they're "bankrupt" morally. Alternatives are finance, ad tech, big consulting, etc. Are YOU working for a non profit?
