You’re not going to get the same prices or priorities from Foxconn or TSMC with a less than 10 million device run rate that Apple gets by selling 300 million + devices. Besides Apple invest billions in TSMC and Foxconn and their other suppliers.
Do you remember that Apple became dominant in the iPod era by buying up all of the worlds supply of 2.5 inch hard drives and later flash chips?
Anyone else is going to struggle to get the prices or manufacturing time from suppliers to produce at scale.
Heck Sony is struggling to make even 21 million PS5 in a year. If Sony can’t manufacture at scale, which electronic manufacturer can?
It’s not just priced for design, it’s processor design, supply chain management, software, software/hardware integration etc.
