We live in the world we live in, and counter intelligence is necessary. The fact that it's privatized is nothing different that what's happening with KBR, Blackwater, Lockheed-Martin, L3, et al. It's more a function of political realities where critical functions are being subcontracted out.
I'd rather have a Palantir than not have one and be outmaneuvered by other geopolitical rivals.
edit: hey, rayiner, fair point. I think that logistics and 'private security contractors' are in a different category than traditional defense contractors. I'm not really sure where Palantir belongs on that spectrum, so I intentional casted a wide net.
