Regardless of whether you consider this to be a symptom of "PC culture," surely most people can see that Disney had to change this scene in 2018, if nothing else then for business reasons. Why tick off a large portion of your audience? (Save that for parking fees!) It's just not good business.
Personally I'm glad I won't have to explain the bride auction to my daughter, since I don't take her to Disney for a lesson on women's subjugation in history, especially when it's portrayed for laughs. That having been said, the new scene is sort of....weird and uninspired.
