Not only that is closed source, but IT IS REQUIRED to have installed google service in order to be able to use that shit app. In the guide about wallets I specified for which app is required or not. So user will know what to download.
I see people using de-googled Graphene or Calyx and then go to install Aurora to be able to install WoS. LOL So you go back to google shit services just for downloading a tracking app.
Why do you bother to de-google your phone if go back to the same shit?
