Given different roles and low numbers of iPad Pro's vs. iPhones, I don't think any cross over assumptions can be made.
The iPad Air as well as the plain old iPad had also gotten standard USB C ports with zero restrictions before this particular conspiracy theory became popular.
If the iPhone were to disappear tomorrow and Apple were banned from ever making phones, Apple's moat would most likely collapse.
If the iPad went away tomorrow, Apple would just lose billions or tens of billions of dollars in revenue and not much else would change.
None of them were from confirmed sources or even cross referenced.
As for a commissioner seriously reacting to it; your local police department is more professional when it comes to commenting on active investigations.
They mainly act like politicians that want to look though in crime. Vestager is a great example of how much PR the average commissioner is willing to utilize, even when they get wiped out of court.
Given that Apple had already been shipping standard USB C ports with zero restrictions starting with the 2021 iPad Pro, this conspiracy theory made no sense.
