Because the mission is visibly abandoned. There's nothing "open" about OpenAI. We may not know how the mission was abandoned but we know Sam was CEO, hence responsible.
The only thing that changed is the reason why the unwashed masses aren't allowed to see the secret sauce: from alignment to profit.
A plague on both their houses.
No doubt OpenAI was never a glass house... but it seems extremely disingenuous to say their behavior hasn't changed.
ie. the original mission was never viable long-term.
