At the moment, life without Google may be a total mess. It has become a strong hold a service to many systems that exist now. We have all been hooked. I think it would be the Chinese (I think they do not care much about Google) that really use HarmonyOS.
I do dispute the fact that Apple has impeccable software. In fact, I do have a strong feeling that I may warm up to it quickly and fall in love, if when I get a hold of one of their devices.
