That’s a fair challenge. I think it’s a little different though - the SoC was one component of the iPhone - so full details of the competing product weren’t being shared.
Plus when the relationship started volumes were small for both iPhone and Samsung phones. As we know Apple ended the relationship eventually.
I struggle to see Lisa Su handing this info to Intel even with some strong safeguards.
I’m 100% convinced now that an Intel split into foundry and CPU vendor is inevitable.
It’s a political if not a commercial necessity if Intel is to provide a viable alternative to TSMC.
