He (and nVidia) have no responsibility to consumers. They have a responsibility to their largest customers and to their shareholders.
I understand this is true in a strictly legal and financial sense. I hope you are simply pointing out a factual statement and not bootlicking for companies with business practices that make your own life worse?
He and NVIDIA should never have been in a position where they can single-handedly dictate where the world's GPU supplies go to. They should never have been able to form a circle jerk economy with a handful of hyperscalers and AI labs. They should never have been a chokepoint for the entire personal computing industry, which is being wiped out right now due to the artificial shortage of critical components.
The lack of regulation and/or enforcement has brought about this completely textbook case of market failure with damaging consequences for the broader industry and society as a whole. It was the responsibility of governments to prevent this exact situation.
But here we are. Jensen Huang and NVIDIA brought themselves to a situation where they are responsible. They should be held accountable for the negative externalities they cause.
