Oh, what you're describing is more about artistic discrimination than giving a low rating for not making good art.
Regarding the profile pic of Belle Rivers, her name is Vanellope Von Schweetz (Wreck-It Ralph), and her game jam recommendation is based on a very reductionist view of the character, simply because she is a Disney Princess and especially because of her fan-service scene in RBTI.
What made Vanellope different from the rest of the princesses was that she doesn't come from any adaptation of any classic fairy tale, she comes from video games (which, by the way, are not exactly free of titles that use the aforementioned) and from the modern era, to the point of proclaiming herself "president".
Vanellope made me question how Disney uses the term "Princess" in all its products, and looking at her design and the theme of the movie made me think that maybe she shouldn't be a princess, much less a Disney one.
Do you know why Randy & Manilla exists? Because it's the work of a big fan who has strongly disagreed with how Disney treated the character (especially in RBTI).
But putting all that aside, it was eye-opening for me.
