Ah, the famous Nuremberg defense. Sorry to invoke Godwin's law immediately, but shifting responsibility away from the people executing the questionable work to the people who either own or consume it is a denial of agency of each and every software professional.
I argue that the workplace of the knowledge worker is not one of blind obedience. Moral reasoning should not be suppressed just because there are other market forces.
My point was that instead of a low-level "programmer" having delusions about deciding the ethics of the company or even industry, perhaps leave that to the public, the consumers. They may get it wrong, but guess what? it's their job to decide what the market wants, NOT yours.
And I didn't say stay and follow orders. If you really believe you are that right, your free choice is to leave.
See you want it both ways. You want to feel morally superior, but want to get paid and eat too. But unless you are willing to really put up something of value, your personal moral objections carry no weight. In fact it pretty much shows how petty you are. Real ethical convictions mean not ignoring or avoiding the personal costs.
So why not change the awful organisations? The ETHICAL way to do that is to change a) the law, b) public opinion, c) show wall street an ethical way to make money, etc. d) compete better and put them out of business.
Stealing time, privately or publicly undermining your employer is not ethical. Stirring up politics at work is not ethical. Or wise.
OP has it right. They want the engineers to talk ethics because engineers are the new druid class... instead of the wannabe preachers in media and the humanities who step further and further away from being able to have an intelligent, logical thought.
The public long ago absolved itself of responsibility for modernity, and that includes the public intellectual class, who now just fingerwag the ones doing actual work.
Especially when most of that moral posturing comes not to even leaving your company to work (at still a very comfortable salary, mind you!) somewhere else, but to protesting mostly minor and inconsequential (and to most of the country, if we're talking about SV and US, quite unobjectionable) things while happily working on projects that actually do have some pretty damning ethical implications (viz. pretty much any Google protest).
