> Obviously you must not be aware that Android is not the leading platform in terms of app sales.
Both are still in the range of tens of billions of dollars. If one is worthwhile the other is too. Android is also by far the leader in number of actual users, which is what matters most to companies like Facebook.
The sideloading process is harder than just installing an app. Most users do not know how to do it and have no interest in doing it.
Google does not allow third party app stores to be distributed via their app store, and I assume Apple would do the same.
You say:
> Most users are not technically capable enough to even go about installing an alternative store.
This is obviously false. We know for sure that average users can install apps.
A store is just an app. Why would installing an alternate store be harder than installing any other app?
Why wouldn’t Facebook just integrate their store into their app?
