The answer it's not really different from the other Disney thread, basically money. Disney it's a big company and it's sole purpose is to make money, of course that doesn't mean they can still make beautiful animated projects, but sadly they just went to the common denominator during the last couple decades.

It's not really that hard to deduce that. For instance, if you want to change the hair color of a character, if you are doing traditional animation you would have to do all over again, while in CGI it's just a matter of a couple of extra hours rendering. Not to mention, since in CGI you are working with models, it's way easier to use camera shots and movement test with your characters.
