<i>Firefox OS was pushing for &quot;apps&quot; to be web apps. That seemed a lot more open to me than pushing for apps to be proprietary</i><p>This argument is made frequently, and I don&#x27;t get it. With a typical web app, you have no idea what the backend is doing, and your data is stored on servers owned by third parties. At any time they can revoke your access, go out of business, share your data with others, or change the app in user-unfriendly ways. An open source Android app that runs and stores data locally (perhaps with an option for cloud storage) seems much more &quot;open&quot; than that.
