This is, in theory, feature not a bug territory. Your CEO did something they shouldn't of (allegedly). The board now fires them rather than having the stock and the company ride or die based on it.
Will the short term stock suffer, sure. Will the company do better for it, maybe/maybe not? I don't totally agree with one great man but I get the idea and once you start working at a certain level you do see products often as a reflection of the values of the top of the chain.
Either way, there's no doubt this is a complicated and "unique" circumstance given the behavior of the US government, and I wouldn't be totally shocked if he DID knowingly break the law and did so with the help of the POTUS, and that's an entire quagmire.
The board/company distancing itself from that makes sense, and bluntly, it's not like jensen staying on was going to save the stock or AI. This is a symptom of what's going on not the cause, and him somehow not being voted out likely changes nothing, even for the board or NVIDIA who are all going to have uncomfortable questions about behavior and decisions even with Jensen out the door. Hell it might be the best place for him.
The others do not have a board capable of outing them. It has, in fact, been tried and discussed at length.
It's not a conspiracy, this is what happens when you don't give one person total control through manipulating the board and stock. You fuck up and get the axe.
