This. We rarely realize that we idolize the wrong historical actors which contributes to our inaccurate evaluation of their deeds. In this case, pointing out Feynman or any other "brilliant minds" behind horrific events and technologies fails to acknowledge that they had detractors in during their time who pointed out these things to them. And they ignored them. I usually try to keep that in mind now. In the back of my mind I'm saying "they knew, someone told them" and lo and behold, if I go looking for said detractors I can usually find them in spades. I'm not defending or excusing anyone. Just pointing out that its unlikely these employees were unaware. But it just doesn't seem likely.
