      Supposedly they are malevolent spirits that sometimes may grant wishes as a reward, not by some compulsion.

        Depends on the story, and IIRC it has shifted with time. But yeah, the general trope is they are stuck in a small vessel, and they offer/are extorted into one or more wishes to free them. Why they are stuck ranges from evil sorcerer trying to enslave them to noble hero stopping their rampage.
