Nobody said the eInk devices can't be illuminated, just that they can't be backlit. "Backlighting" is - as its name suggests - having a light source behind the screen, which shines through the screen. You can't backlight an eInk screen for the very simple reason that it's completely opaque.

Illuminated eInk devices are frontlit. That is, they have LEDs above the screen, whose light is directed onto the screen from above by a light diffuser.

This is not pedantry, but a fundamental difference between lighting systems.
