Disneys Blatant Sexism?

After reading an article about Disney's "Transformation"on the disney princess Merida I've learned that Merida was created as a basis of the creators 13 year old daughter, I've also learned that a lot of people are protesting the new transformation, i myself are one of them. I have also learned that disney is over stepping their boundaries on things. I like that the article was very informative on the actions disney has been taking, I also like the fact that they have the before and after picture if the princess. Why is disney doing this? do they have TOO much power?
