I think what's more important is somehow getting Apple to allow alternative app stores in their phones. While Android phones are the most popular in many (most?) countries, iPhones are still very common and make it so solutions in one distribution platform don't extend to all phone users. Once a competitor is able to operate in both Android and iOS, I think we will see a real threat to official app stores, whether it…
Like it or not, pretty much the whole reason Apple only has The One True App Store™ is to ensure at least some amount of review of QA is done before unleashing apps on its customers. Does that get abused? Arguably - yes. Is it overall a good trade-off? Depends on your use case. Want "full" control of your whole mobile device?

Technically, Android doesn't have a One True App Store. But in practice, Google Play is the standard app store and 99% of users use it exclusively, at least in the West. It is in fact the one true app store for Android.
So Google does in fact control the Android app store (the one that counts, anyway). The reason why Google Play has so many shitty apps is because Google simply doesn't care about curation in the same way Apple does. That's true for every Google product, by the way. They strongly favor algorithmic curation, while Apple also relies heavily on human curation.
If Apple allowed alternative app stores, nothing would change as far as the standard iOS app store is concerned. 99,99% of users would keep using the Apple app store unless there was a very compelling reason for using an alternative.
