This is good for developers as well as users.

Developers releasing new products are competing with 100,000 new/updated apps per week. Old, unmaintained, and worthless apps pollute search results, making it more difficult to find good apps from good developers. These same crusty apps inevitably result in poor user experiences that punish people who try new apps. Users and current developers shouldn't be saddled with the burden of competing with the ghosts of developers who gave up in 2017.
