The industry has a potent weaponization aspect/risk to it, that the tech overlords recognized a very long time ago. They also know how parts of the tech landscape (eg SV workers) responds to such things as AI being used for military purposes (or similar). So naturally the people in charge of big tech (including the financiers) have to try to lure that labor in to creating what they want, via misleading fakery. Thus it is you get the non-open OpenAI.
