The whole business model of living off of App stores, controlled by tech giants, is flawed, and no sane person should ever make this their sole source of income. It's like being held hostage.
I also have the same (controversial maybe) opinion, the mobile stores are good enough for a hobby developer, they are not mature enough for real businesses.
I'm going to launch another mobile app for some side income in the future but I'll never launch a real business based on that, that's for sure.
It's more like working in a world where there are rewards and risks.
There is a good argument that the world as a whole would be better off without the current App Store model, but it makes sense for individuals to aim to profit from the existing model.
The real world also has rewards and risks. It also has a judicial system where the actions of both parties are weighted and judged by an independent party. In that world, one party cannot summarily forfeit an outstanding balance owed to the other party.
