"The light is necessary to me so I don't forget to turn the box off when I finish watching TV." – a customer

Teaching people to believe they need to turn off their settop box when they're done watching TV, combined with training them that an "unclean shutdown" of their computer will cause it to eat itself for breakfast, are just two of the terrible sins our kind has committed against humanity.

(As a ridiculous compensation for this, in many modern settop boxes, the light and power button exist mostly as a placebo.)
