If it was anyone OTHER than Samsung.
The 1st iPhone was Samsung SC6400 family.
Samsung may have many good reasons to use their own chippery. If Intel made ARM phone chips and phone would they buy a Qualcomm cpu?
Though Samsung do use other people's CPUs when it suits them. They are thus not like Intel.
So really Qualcomm seem to be over-reacting. Unless Samsung is going to sell to all the other phone makers in competition to Qualcomm next iteration.
