These stores are not curated. They can catch the most egregious things, but they also are not really "safe" either. It would totally be worth 30% of my payment

These stores are not curated. They can catch the most egregious things, but they also are not really "safe" either. It would totally be worth 30% of my payment for a truly curated app store. However the Apple app store takes a lot of income for providing a negligible quality filter, updates, and taking payments (most payment processors take single digit percentages).
