Android in China is a very very different Android from what the west is used to. If their Authenticator and Identity Pass app are stuck to Google Play Services, it's surely more risk adverse to give all chinese employees iPhones than to rewrite those apps to take into account the very large amount of OEM SDKs and secondary platform/ecosystem SDKs just to get push notifications everywhere.
