Their stated non-profit goal was to benefit all of humanity. Changing OpenAI to benefit their financial backers in a formal sense could be a loss of nearly unbounded value.

Which is probably why they created another, for-profit, entity.

You can argue that it's unlikely the for-profit conservatorship of the non-profit is incompatible with that goal, but legally that becomes very much grey area.

As i wrote in my prev argument, they assumed that as non profit, they wouldt' get the capital needed to even be a frontier lab.

So nothing to loose if their model wouldn't have worked anyway.

And at the current state, its better anyway that China is pushing the non-profit/humantariy aspect of open models.
