I have nothing against hybrids as long as they are properly labeled, however, a lot of breeders do not want to lose a season with a female that may not lay eggs from a low probability cross: so they will mate her with a same species of male (just in case). Depending upon genetic assortment they might end up with a hybrid that looks a lot more like one species than the other and label it wrong.
This happened to a friend of mine and he ended up with a female SuperBall: when confronted the breeder explained the situation to him. My friend did keep the female and failed repeatedly to breed her back to a ball python in the following years, he showed me a video and male ball pythons exhibited sheer terror when in any proximity to her. Last I heard she was a display pet only.
