I know you're trying to prove your point, unfortunately you're incorrect.
If what you are saying were true, Apple wouldn't be hiring Wireless IC Engineers. The job posting below for example, specifically calls out baseband design. Apple has been hiring these engineers for years, well before this Qualcomm incident.
A couple of my university cohorts are baseband engineers and it's entirely normal for big customers to dictate the design direction of modems from Qualcomm, MediaTek, HiSilicon.

Your assumption is engineering decisions are always prioritized.
In the real world, many leaders view their company using a wider lens. Tim Cook as a supply chain guy, knows using a sole source for modems is a mistake. These lessons were learned over 30 years ago when IBM demanded Intel share their x86 architecture with AMD to avoid overdependence on Intel. The lesson today is no different. You groom your second supplier such that they compete with each other. Crippling Qualcomm modems in the short term to groom Intel is a no-brainer if Apple wants to win in the long term.
