In addition to the visual changes, the characters’ personalities were also updated. Ms. Green, known for her self-awareness and outgoing nature, now has a more inclusive and friendly demeanor. The redesign aimed to emphasize her confidence without the previous overt focus on femininity and sexuality, which had been a point of contention among audiences. This change was part of a broader effort to reduce the sexualization of female mascots and promote a more progressive representation.

Huh.
I think they are referring more to the (really fucking stupid) backlash against those changes by the Fox News crowd.
They tried to make it a culture war thing. The alleged “sexiness” of a cartoon M&M being reduced. They flipped their shit.
