MAYU's Exti tunes Vocaloid so their idea of marketing her is to do that. Despite that, she isn't too much n the spotlight. Forcing popularity can have its draw backs. ITs the same situation SeeU's in where their pushing her. You risk everyone getting fed up with something no one really wants.

But it can mask a otherwise flop product and make people buy something they wouldn't otherwise do so. But still, it falls back onto the idea of selling a vocaloid by getting others to use the vocal.
