Why do some plugs have obviously inefficient designs, e.g. cover multiple outlets, or only fit in the very last spot because they bend at a right angle downward?

Part of it depends on the type of power the device needs. The power in your wall is alternating current (AC) but some things need direct current (DC). The latter needs something to convert the AC power to DC, which is why many power cords come with a bulky box that often covers multiple outlets.
