As a developer I don't want to publish my app to different stores. Each new publish costs days and thousands of dollars in time. Also development becomes much more expensive. And usually those stores have pure garbage of an APIs.

As a consumer I don't want to search an app I need in 5 stores. It is a pure waste of time and I have much better things to do.

Fix existing store? Sure.

Let it rain with new stores, so to speak? No.
