I think it's less of a gray area than that. Anyone at Uber who worked on Greyball, perhaps telling themselves that they were thwarting an oppressive government who was firmly in the pocket of the taxi lobby, was naïve at best and deceiving themselves at worst. Maybe some people got caught up in the cat-and-mouse game of evading authorities and failed to question whether what they were doing was "Good." That's the author's call to action in this piece: to remind us to step back and evaluate what we are doing in an ethical context.
Things seem less gray for the author's second example- developers at Palantir designing a workflow to help ICE round up immigrants. Of course there is room for counter-points in an argument about how best to handle an immigration crisis in any country (I say "crisis" because I see it as a crisis that we are doing so little to help) but at the end of the day, our individual actions need to be made on the basis of an single ethical black-or-white question, and history and indeed the present will not look favorably upon those who fail to act in the best interest of their fellow humans.
