It would be just as trivial to create a 3D bar chart that has the same effect as the example (accurate, self-referential, and confusing because of the color/label mismatch). While clever, this example isn't an indictment of pie charts, because it clearly shows the relative proportions of two quantities (as would a bar chart).
There's two different links in these comments that explain at length why pie charts do not clearly show relative proportion. This is even less true of 3D pies.
