Wouldn't characterize it as cheating. The lower frequencies can be carried in a wire and are popularly considered to be electric in nature. Above a certain frequency wire becomes a poor carrier of the signal and you have to go to other means (waveguide, air, optic fiber, etc.) But, as your chart show, it's all the same electromagnetic wave, differing only by frequency.Using something outside of the electric type is cheating! light has far higher natural frequency so modulation or oscillation with it are not exactly electric bit electromagnetic in nature.
