Actually, I agree with UrougeFan. People of Dressrosa already knew that Scarlett was alive and living with her husband Kyros and their baby Rebecca. So, once Doflamingo misled the citizen to believe that he was the savior of Dressrosa from the evil king and his children, I believe people just turned their back to Rebecca.
