The thing that is needed is a cloud storage API that is mandatory by law and is required to be honored by the OS. The OS vendors create a virtual cloud storage layer which has a backend that can be implemented by any cloud storage provider and then all the apps use these abstractions when loading, saving, and so on their data to the "cloud." Which can be anything from a third-party online service to a self-hosted solution. It should be implemented in all apps that support cloud-based content, music, books, movies, home environmental data, medical data, exercise history and the like. Silicon Valley has developed an arrogance, and they need to be reminded that they are subject to laws and regulations like all of us and that it could be much worse for them if they continue to be wankers.
