Intuitively I feel like it's something like the light bulb. For a while, bulbs had to meet efficiency standards. These standards were configured such that they didn't technically exclude incandescent bulbs, however, for an incandescent bulb to comply, it would have to be driven hard and thus comparatively short-lived. (for context, incandescent bulbs last something like 4x as long if you let them be 10% dimmer)
