I think the next thing is adding the ability to download all your data, so you could switch to a different service. There are many advantages in having companies manage your data and software over time. The pernicious part is when they make it "sticky" by preventing you from accessing the data you have created with their service. If you're able to access your data, you at least have the option of downloading it at any time and canceling the service. Whether you can use it or not in another service is a big unsolved problem. However, it is not unsolvable. Another set of companies could easily evolve that provide transfer services.
