For universal USB-C power support that works with modern power bricks, you need to tie 5k resistors to two pins of the port on the device. This tells the charger to use 5v. I can’t tell you how much cheap stuff out there omits these. They cost almost nothing but they still screw this up over and over, and people blame the standard or the cable…
I don't think it's cost reasons these are being omitted. The customer refunds would easily exceed the savings. It's most likely designers just swapping a micro usb port with a usb c one in an old design while making no other changes and seeing it works with the A to C cable they have.
