I have no idea whether he violated export controls. It sounds plausible, but there's no evidence to this yet as far as I am aware. I suspect he may be stepping down out of shame for his actions, especially since his children have roles in the company, but I have no insight into his mind or personal life.

So, he was either complicit or ignorant.

It's amusing how people mentally backflip through the dots like they're unwilling to do any mental math that might shatter the soothing tail of people just being mere happenstance and human rather than some power above others.

I think you should read more reports on both the circular financing and the smuggling of chips into China. Or the evidence of the Chinese models being trained on blackwell chips.

All the stars are there, either he's complicit or ignorant. Choose which you're asking to lead you.
