That's not true. It'd help a lot. Apple can use their cable and simply not say that it's USB3/TypeC/FancyX. No one would care if it would actually work.

But at least there were clear markings for those who care.

It would take up about 2 cm on each end of the cable, a set of bands, like a barcode. It doesn't even have to be that strikingly different in color.

I just want to find out who at Dell is responsible for perpetuating the use of black markings on a dark-grey background.
