It's not that, either. Low-margin, high-volume contracts are the worst business you can take. It devalues TSMC's work and creates an unnatural downward force on the price of cutting-edge silicon. By ignoring Apple's demands they're creating natural competition that raises the value of their entire portfolio.
It really is about making better hardware. Apple would be out-bidding Nvidia right now, but only if the iPhone had equivalent value-add to Nvidia hardware. Alas, iPhones are overpriced and underpowered, most people will agree.

I'd argue this from almost the opposite direction - there is no value-add for Apple because high-end smartphones exceeded the performance requirements of their user-base generations ago.
Nvidia has a pretty much infinite performance sink here (at least as long as training new LLMs remains a priority for the industry as a whole). On the smartphone side, there just isn't the demand for drastic performance increases - and in practice, many of us would like power and cost reduction to be prioritised instead.
