Most people that think that Blackwater/Xe/whatever they are called today is bad also think that the government decision makers deciding to employ them are/were bad, at a minimum in the context of that decision, and quite frequently that the whole, long-term, multi-decade policy of progressively outsourcing formerly-military conflict-zone functions to civilian contractors is a bad trend driven in no small part by corrupt business-government relations in the military industrial complex.

So, saying "Well, the State Department hired them, so they must be good" is, well, kind of ignoring the entire basis of the opposition.
