I’m just a working stiff and I’ve refused to do things for my employer that I found unethical. Sandberg is a billionaire who never need worry about anything, ever, not her children or children’s children. What does it take for someone like her not to support obviously shameful behavior?
I think it is too convenient to differentiate between work and personal views when the view is unpopular but not draw that distinction when the view is popular.
The fact that you believe that its shameful for a particular business leader to espouse malpractices is a testament as to why PR agencies who manage perception of individuals as well as institutions charge such hefty money.
