"I'm sure Physics, for example, is full of people with connections to defense, and we know that lots of top Mathematicians have worked for the NSA."Not to mention the strong historical Silicon Valley links to the "defense", prison, law-enforcement and intelligence industries.
One also has to ask what weight should be given to indirect cooperation with and enablement of said industries. If one is not working for a defense contractor, but a supplier of said contractor, or if one even takes money from or in any way benefits from these contractors or contractors of contractors, what's your culpability? Where do you draw the line?
I am also reminded of "IBM and the Holocaust",[1] which is deserving of its own HN article.
