Those kind of apps don't have the same purchase cycle as entertainment items like games, movies or books. They don't grow less valuable the more hours you spend using them (in fact, they generally become more valuable the more you've invested in learning them.) Folks either want to rent entertainment , or buy it knowing they can resell it, because they know that the act of consumption will devalue that item for them but it will retain greater value for others who have not yet consumed its entertainment.
