No one knows what is discussed.
Half glass full vs Half glass empty.
The same report can also line it this way and it make perfect sense.
Apple COO goes to visit CC Wei @ TSMC to discuss whether they are still going to manufacture all their product with TSMC. (Half Glass Empty)
You needed to understand less than a month ago (24 Apr 2024 vs 21 May 2024), CC Wei @ TSMC visit California where Apple is located. It is rare that CC Wei @ TSMC did not schedule a meeting with Tim Cook, its largest customer by revenue by far.
It is understood that the relationship of TSMC and Apple as a whole is good, therefore it is a surprise that if Apple still going to have all product manufacture @ TSMC then there are little needs to reconfirm things working well. The engineer down there will do all communication.
More likely so is Apple do want to change something, no matter it is pricing / level of partnership / unhappy things of current situation (e.g. product availability, future roadmap, capacity, etc.), and this something can not be resolve over the phone.
I can write a report tomorrow headlined Rumors: Apple want to reduced it reliance to TSMC and seek for a second foundry.
