That just means the device vendor isn't exerting the necessary pressure/valuation on the SoC manufacturer.

Of course the SoC manufacturer is gonna try and get away with bare minimum of work for absolute maximum of profit, just like the device vendor. The pressure needs to start at the end of the chain (which is end users) :/
