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.
Applied ethics, are what most people mean when talking about Ethics. They are industry specific and defined by the industry. Normative ethics are near equivalent to morality. Meta-ethics are what Sam Harris and Jordan Peterson like to argue about.
This is very simple for most professions that are defined by licensing or certifications which require conformance to a code of ethics. Ethics in law are not dissimilar from ethics in medicine. In software there is no commonly accepted code of ethics. Instead there are "terms and conditions" and "employment agreements", which typically do not isolate ethical standards to the software profession.
