Why does the Razer Huntsman use the space of the LED indicators to put the logo?

Correctly: "Why do these things swap places?".

Hands can cover lights.

The layout does not have to be the same as for keyboards with additional controls.

Visibility can be improved, but that does not matter, as it is not worth sacrificing covering the gauges, to simply focus a closer position (and for the visually impaired, the user does not have to approach to examine the icons of those lights).
