Plus... Apple kinda wastes it. Not to be judgy, but we don't need 2nm chips to hardware-accelerate Netflix and Pornhub. The iPhone is locked-down, there's no worry that it will be a poor gaming platform or disrupt valuable workflows. A new iPhone chip means nothing anymore.
Between the $99/year sideloading, Liquid Glass and fighting fruitlessly against CUDA, I think Apple needs a break to reflect on why their software strategy is so unpopular with everyone. The hardware advances are doing them more harm than good at this point.
TSMC is a for profit business. Why would they care about the moral virtue purity of the applications running on their chips? Seriously illogical statement
