So a Qualcomm refuses to sign such a contract. What are going to do, use Mediatek for your flagship?

On the Porters five forces scheme of things, the SoC vendors have much better bargaing power than device makers.

There is a free market out there.

Long time ago, people also though ARM was going to close doors.

If Qualcomm refuses, other would gladly do and eventually become good enough for Qualcomm to either change their mind or become irrelevant.

Talent and IP are in extremely limited supply. Your alternatives are mediatek and spreadtrum.

So be it.

The majority of my devices don't have Qualcomm.
