Placebos everywhere

I found this article about placebos kind of charming. Placebo elevator buttons (I knew it!) and placebo “walk” buttons at intersections (I suspected it!). But I wonder: is this really the placebo effect? Shouldn’t a true placebo somehow provide part of the benefit that the real thing is supposed to give? Placebo ≠ faking it.
