By "did not help", you meant "did not completely 100% solve the problem", right? In the same way that seat belts do not help traffic fatalities because there are still traffic fatalities?
No, I meant that it did not solve any issue in this area at all, fake iPhone are as easily available as other fake brands. It's 0% affecting fake products which have their own separate supply chain anyways.
Again, the existence of X does not mean that all efforts to reduce the incidence of X were completely useless and therefore should not have been undertaken.
Fake iphones don't and won't use any genuine parts. So locking said genuine parts achieves absolutely nothing against fakes, so yes that does means that if that's the goal, it's pointless.
It's not about fake iphones. It's about taking a real iphone and swapping a part for non-genuine one that does something you don't expect (or find out)
