Helen believed she was doing her job according to the non-profit charter, obviously this hurts the for-profit side of things but that is not her mandate. That is the reason OpenAI is structured the way it is, with the intention of preventing capitalist forces from swaying them away from the non-profit charter, in hindsight it didn't work, but that was the intention (with the independent directors, no equity stakes, etc)
The board has all my respect for standing up to the capitalists of Altman, the VCs, Microsoft. Big feathers to ruffle - even though the execution was misjudged, turns out most of its employees are pretty capitalistic too
