This is spot on. I made very similar comments last year, in this piece on MacStories:
Overall, the App Store’s focus on games and “entertainment tiles” speaks for the minds of consumers who aren’t always using their devices as business and productivity machines. “In the end, Apple has to prioritise customer satisfaction, over developers”, said Mayo. “This means they almost have to focus on the big, wide appeal, titles. Showing niche apps simply to give developers more exposure would not be serving the interests of most users”.
