Have you isolated yourself completely from reality? I don't even know where to begin on this. Let's start with the fact that China is pumping out some near-frontier models and open sourcing the weights- and they don't even follow capitalism and the owners aren't billionaires. Really there are like four models in the USA that are "owners/controllers", and only one is even slightly controllable by its CEO, though none of the frontier models can last a week without the support of entire teams.

Why on earth would you want to siphon off the proceeds of AI development to (ok my bias is strong here- mostly corrupt) "ideals" like world hunger and cancer research (that probably get more dollars annually than the sum of actual profit any of these companies will ever get). That would just instantly kill the ability to improve AI at all, and the world could possibly be better for a few months?
