The mob was outraged at Nintendo for toning down the sexualization in American versions of some games, particularly sexed-up depictions of teen-agers and eliminating the features in one game that allowed players to change the sizes of women characters’ breasts. They blamed Nintendo employee Alison Rapp, and harassed her until she was fired. Rapp actually lobbied to keep the breast-size-change feature.
Yes, this is a real thing that actually happened.
