Because Don Rosa would probably have a full on reeeee fit if they had to change the slightest thing just so it worked a bit better as a tv show. He would probably vehemently object to David Tennant doing the voice of Scrooge because he was involved in Ducktales and/or the animation style as well. He would probably disown the whole thing very publicly as a result, which, while not always a surefire killer of a show, will definitely hurt the shows potential viewer numbers.
