Earlier quoted context omitted.
I'm playing the devil's advocate here but there are also a lot of tech workers who do not regard building such a database as unethical. A common fallacy on HN is to assume people who hold differing views necessarily do so egoistically, which is sometimes true but not always.
Yeah it's entirely possible that there are a small percentage of tech workers who would fully support this type of move. I too have noticed HN users seem to just assume everyone shares their views.
What makes you think it'd be a small percentage? I didn't notice the NSA having trouble attracting very bright staff, apparently it's the opposite: they were able to get their pick of the best despite uncompetitive salaries. And the NSA has spent years taking part in targeted assassination programs of innocent people who weren't in US jurisdiction, had no charges levied against them and never had any sort of trial. They were just drone striked.
