Literally none of what you said is true.

I have a key that toggles between keyboard layers, of which there are three. Different layers are assigned different colors. If I forget which layer I'm on then I can just glance at the keyboard and know. The LEDs are similar in purpose to a Caps Lock indicator.

And for the third layer, which has only a dozen or so keys defined, the keys that are defined are lit up in their own color. This layer sees less use than the first two, so it is helpful guidance to remember which are defined.

I have criticisms about the keyboard -- Moonlander -- but none are about the LEDs. The LEDs are useful and not simply moronic eye-candy as you seem to imply.
