I'm a decade older so maybe I missed the memo but I think you'll have a hard time naming tech companies that actually refused to work with the military, which were large enough and important enough to be in danger of selling something to the military (i.e. not Be Inc. or Beenz.com)

Clearly, all of the traditional big leagues were lined up to take the Army's money. IBM, Control Data, Cray, SGI, and HP all viewed weapons research as a major line of business. DEC was the default minicomputer of the DoD and Sun created features to court the intelligence community including the DoD "Trusted Workstation". Sperry Rand defined "military industrial complex".
