DoD/DoW can't strong-arm these companies into unreasonable demands if they present a united front... and that's exactly why collective action (or even unionization) matters.
If the government really wants to, it could try building its "Skynet" on open-source Chinese models.. which would be deeply ironic.
So your position is that the United States doesn't get to have it's own Skynet, because Skynet is bad, and that if it really wants to it should fork the Chinese Skynet so that it can have a Skynet if it wants it so much.
Do you see the problem here. Genuinely don't think we would've won WWII if these people were running things back then.
This is ridiculous. These aren't unreasonable demands and the government has tools to compel tech companies to support the country regardless of any "collective action" shenanigans -- ask your AI to tell you about the Defense Production Act and the history of its use.
