Well, if Huawei would say a) here is our store b) your app will be marketed to Chinese population (as long as your backend servers run on Chinese infra)

then, I think they have a chance to attract app developers. Otherwise, I doubt it.

For Chinese market, Huawei don't have anything to worry about. It is likely gain more "Chinese" market share from this.

For the rest of the world, it would be completely different story. It is hard to imagine Huawei won't loss huge market share from the EU and rest of the world without Google's Play Store.
