Ok I'm all for a good app store rejection story but this sounds pretty suspect: “any app designed to help people use their phones less is unacceptable for distribution in the App Store.”

It's way more likely because there isn't a public API for changing the application icon on iOS (at least until 10.3 https://developer.apple.com/reference/uikit/uiapplication/28...)

...and even when once there is a public API. It is certainly against app store rules to infringe on the trademarks of popular social network companies for what you use as your icon.
