The 'abandoned' apps are also often actively advertising, so possibly they do something that causes it. I see tens of thousands of apps churn like that a month. They're not some quite app that a developer stopped updating, but something actively having ads bought for it that is then taken off market.

For example these apps advertising in October 2026 https://appgoblin.info/reports/ad-user-acquisition-2026-octo...
