I’m not saying anyone should walk away from money. But the same people who want Google to walk away from the world’s largest country aren’t willing to walk away from thier stock but expect Google executives to make financial choices for moral reason.
I don't think walking away from all your stock vs. a company walking away from a deal that would account for a small fraction of its profits is a fair comparison.
A more fair comparison would be asking if employees would be willing to have their stock decrease in value 10% in exchange for their company being more moral. I expect many employees would take such an exchange, although not all.
But those employees who _did not_ care about morality also would have their stock decrease by 10% in value due to no fault of their own. Therefore, it's only ethically correct for those who want to take the stance to also accept a decrease in stock compared to those who didnt.
