It's mostly about cost and market access to China.
Most smartphone supply-chain for Samsung and Apple exist outside China -- primarily in Japan (camera, sensors), South Korea (DRAM/NAND, OLED), and the US (various ICs fabbed at TSMC in Taiwan). There are quite a few reliable estimates/teardowns showing that these three countries account for close to about 90% of iPhone BOM (bill of materials). That's one reason why Samsung's smartphone unit was able to pull out of China without much disruption back in 2019 -- ie, low dependence on China.
I feel that Apple has pushed this misleading narrative a bit too long to defend their massive China outsourcing.
