I think you missed the point of the articles if you indeed read them. The passive "damsel in distress princess needs rescue" trope is what was being discussed, and its not a vendetta, its was to say that these characters aren't on dimensional and need to be save, they can have more agency. And Disney themselves tried to move away from using this type of princess trope way before the 2010s. Its why you started to see Mulan, Belle, Rapunzel and many other strong female princess character emerge.
Society and times changes, and so does views on old tropes that are no longer popular.
