You are right. This was settled with the Nuremberg principles and code
in the wake of the last world war. Group apologetics are cowardly and
unacceptable. People of excellent character, some of them genuine
leaders, step up and accept responsibility for the moral failures of
organisations they head. Those "merely following orders" deserve no
protection.
We must stop blaming "the system", or "inevitable progress", or
"capitalism", or whatever abstraction. It is terribly weak and
avoidant to do so. It seems perfectly fair to put names to actions
having broad effect. I think the (as you say) _few_ people who make
far reaching decisions in technology deserve treating as de-facto
public figures, as worthy of public scrutiny as political
representatives.
Want to "invent" some disruptive new technology that changes the
world? At least have the decency to put your name to it, stand by it
and defend it ethically. Otherwise what you're doing looks more like
terrorism than science.
Actual individual _people_ make awful decisions, knowing that they are
awful, and hoping to get away with it through "safety in numbers". We
should welcome whatever puts moral pressure on such individuals to act
properly, and not to hide behind their "gang". Corporations have
become a rock beneath which rather little sunlight shines nowdays.
