The CV only contributes half it's mass to unsprung weight, and this system still requires a drive shaft and either a CV or u-joint. But with more mass at the hub.

Typical hubs are still lighter than this, because this setup still requires the hub structure, it's just adding gearing out there.

Half of the hub is unsprung, the transition between sprung and unsprung is at those fancy articulating planetary gears. The drive shaft is definitely sprung, it and the motor is completely static relative to the battery and everything.
