I think Apple hardware must be incredibly underutilised across the board. Every new generation of iPhone or MacBook they boast about lofty performance gains, but who is actually complaining about their iPhone not being fast enough? Nobody I know pushes their iPhone so hard it starts to lag. It's not like you can really do anything computationally heavy on your phone besides games, but people mostly play simplistic 2D games on iOS anyway.
Having performance available when you need it is the alternative to waiting.
Even a simplistic 2D game loads data, runs routines, and while the person is doing that they expect the phone to stay connected to a network, keep up with notifications... you act like Apple is doing something bad.
Intel/Chromebooks still are being sold in the USA at Best Buy with the Celeron N4000-series and Pentium-4200 series chips if you prefer to have zero performance overhead on your devices.
