Every WMD program in existence? The apparatus of our surveillance states? Private companies and wealthy individuals would not pusure these things because it would be illegal and also pointless. Only governments want and pursue stuff like this. Of course, plenty of government directed research and government funded research is positive, but the private sector is intertwined with all that (funding and execution) and it's not true to say just because the government funded something it wouldn't have happened otherwise. At the extreme you have states like USSR and North Korea that spend almost everything on ghastly projects.
