They probably also changed to no dessert because as many people already said, they would get the dessert and eat it later which means you weren't buying that fruit or any other snack later on in the day. A piece of fruit is covered as a snack under the snack portion of the dining plan, but not fruit cups, cheesecake, danish, etc. so by having dessert as part of breakfast (who eats dessert at breakfast anyway?) Disney was probably losing money since people weren't buying snacks later on in the day.
