1Password IGNORE Great china market？

"1Password for Android is distributed through Google’s Play Store and it includes an optional in-app purchase called the Pro Features that is processed through Google’s Play Services. Because of this requirement, our app is considered as a paid application and is not available to download in countries where paid apps are not supported by Google’s Play Store." "We do not host the APK file on our servers because of a couple of important reasons. 1Password for Android uses Google Play services for many operations within the app like processing the in-app purchase, crash reports, and the QR code scanner when you sign in to an account. It would also require you to manually manage updates if we hosted the apk, so you would need to find out if a new update is available on our site, then go to our website to download the latest APK to install it. One of the other big reasons is that unknown sources needs to be enabled on your device to install anything outside the Play Store, and it's disabled by default for good reasons."
