The State Department is maximally non-neutral, they are explicitly looking after American foreign policy interests. That is their raison d'etre. It simply is not possible to be less neutral than the State Department. They're as not-neutral as the US military.
Those corporations are not exactly shining examples of neutrality, but by simple virtue of being multinationals which do business in many countries, cooperating with and abiding by the laws of many governments, they are more neutral than the State Department itself. They are not explicitly and overtly set up to serve a single particular government, although there is good and ample reason to believe they covertly do so. I don't think anybody believes these corporations are strictly neutral, but to claim they're less neutral than the State Department is quite absurd.
