Intel used to play the "gimp your products and create lots of fake segmentation" game when they had a comfortable monopoly lead. Look at them now. A cautionary tale for Nvidia.
I'm not sure it was purely causal, but it was definitely symptomatic of a company that was so comfortable with its monopoly position that it focused efforts on maximizing value extraction from existing products vs new product innovation. Over time this shift in focus certainly contributed to their slide.
So what’s the lesson for Nvidia?
The FTC monopoly team has fangs now, so behave or get broken up in the next few years.
