If your app relies on a 3rd party for survival, you’re building a feature and you’re a dead man walking. You don’t determine your future, the 3rd party does. They can cripple you by competing with you, or simply changing their Terms of Use. Stop coding, stop improving the product, put down the keyboard and step away from the desk.
Think of a new product, something entirely yours and build it. Build it like the wind. Build something that you can own.
