Why did the habsburg emperor Joseph ii react negatively to Mozart's don Giovanni?

Emperor Joseph II reacted negatively to Mozart's "Don Giovanni" primarily due to its controversial themes, which challenged societal norms and moral values of the time. The Opera portrays a libertine who ultimately faces punishment for his immoral behavior, yet its depiction of seduction and social transgressions may have been seen as problematic. Additionally, Joseph II had a vested interest in promoting operas that aligned with Enlightenment ideals, and he may have felt that "Don Giovanni" did not sufficiently uphold these values.
