With Altman gone and the direction of the board being to limit commercial growth, their investment is at risk, and their competitive edge will evaporate, especially if businesses switch to other LLMs as they surely will over time. Altman will also become a competitor.
If instead they are able to pull off a complete transformation of the nonprofit and oust Ilya, they will also lose a core technical leader and risk their investment while being left with the odd dynamic of a parent nonprofit.
Perhaps they could orchestrate some kind of purchase of the remaining portion of the subsidiary. Give Altman the CEO title and move forward while allowing the nonprofit to continue their operations with new funding. This doesn’t solve the Ilya problem but it would be cleaner to spin it off.
