The problem is there are a TON of low-effort apps that are free and have ads. So if you want a good app you have to trudge through a ton of them in search results to find an app that isn't effectively a tool to trick people into ads.

If you could choose to see only paid apps or those with IAPs you'd have an easier time finding apps that weren't trying to shove an ad in your face.

Some apps do ads very well. Some acceptably. MANY do not. AT ALL.
