According to section 3.3.2 of Apple’s developer agreement, as long as you are using the CodePush service to release bug fixes and improvements/features that maintain the app’s original/presented purpose (i.e. don’t CodePush a calculator into a first-person shooter), then you will be fine, and your users will be happy. In order to provide a tangible example, our team published a (pretty cheesy!) CodePush-ified game to the Google Play Store and Apple App Store, and had no problems getting it through the review process.
Because Cordova apps are executed within a WebView, and React Native apps are executed within JavaScriptCore, from a technology perspective, these runtimes are unique in their ability to leverage dynamic code downloads according to the aforementioned Apple developer agreement.

Seems to me it's effectively bypassing their checks - a developer can release v1.0.0 to the app store, never again update it, and push updates via this?
