Moreover, getting the word out on such issues is exactly what you advocate; it is a part of the 'spy-vs-spy' people doing their job.
The network of suppliers is extremely extensive, and expecting the CIA to squander time individually contacting every single sub-subcontractor, or even only the set of ITAR-registered producers is silly.
I would go so far as to say that the threat against you even from overt discrimination is less than the threat from our society being undermined by an unopposed attack on its foundations.
For everyday workplace/community culture, we in the US have a long and ongoing history of biases and poor treatment (including in the workplace) of people belonging to identifiable groups that have been singled out as somehow threatening or lesser. Maybe the pattern repeats. Or maybe the pattern doesn't repeat this time, but many people in the group fear it will, and that's not good for workplace/community either.
