“Apple has reportedly refused to accept a price increase from its sole chip supplier, TSMC, according to Economic Daily News.”

I guess it comes with the territory when you’re TSMC’s biggest customer, accounting for a quarter of their revenue
But on the other hand, as the article says, TSMC is the sole chipmaker for Apple and seeing what Samsung Semiconductor made out of Snapdragon 8 Gen 1 Apple doesn’t have much choice either in choosing someone else. So I’d say it’s a pretty interdependent relationship.
