It has less to do with "oligarchs" and more to do with protectionism over domestic industry: retain jobs in America, preserve worker income taxes revenue, capture taxation of corporate profits, tilt the scales in favour of an American business becoming a global exporter of their products, keep development of high-tech assets under American regulatory control.
I'd expect all the free-market capitalists and libertarians to make a lot of noise against government interference, even if the purpose is to retain domestic jobs.
