I am being objective. If the political opinion was not formulated by senior leadership and passed down through management then it is not likely, at least at the time of expression, the politics of the organization. That said, it is personal politics.
Ethics is not defined by the industry. Ethics is quite literally perceptions of right or wrong in accordance with organizationally defined rules. Right and wrong where rules are either not available or not defined is instead the more generalized term morality. In the example of Google employees' boycott of the drone contract the political action was a moral judgement that graduated to an ethic once senior leadership made a decision.
