I think this is secondary to a widespread loss of confidence in our nation's political and foreign policy apparatus to do what's right for the average American. "Working for the military is evil" descends from a post-Vietnam, post-Iraq, post-Snowden worldview that presupposes that the military will leverage technology it has access to in unexpected, undesirable, and broadly harmful ways.
Well that and it's indicative of the broader American social dysfunction that they are chronically incapable of holding themselves or their (still surprisingly democratic) government accountable and so everything is always about "the corporations".
Every problem is meant to be solved by what corporations do or do not do.
