I think the problem is that product manufacturers try to make everyone happy with a single product. They gradually expand the product's definition in an attempt to get more and more people to use it. The problem is that one of the reasons why the initial users liked the product was that it was simple and didn't have a million features. So you start to lose them, or they like your product less.
