The change to the Content Policy, apparently shown to developers when they log in to the Play Store, admonishes them to not coerce their users into skipping the store. "An app downloaded from Google Play may not modify, replace or update its own APK binary code using any method other than Google Play's update mechanism," the new policy reads. "Google Play is a trusted source for Android application downloads, and we are committed to providing a secure and consistent experience," the note concludes.
