Another thing why I hate app stores is that they have ratings and reviews. While a good idea in theory, in practice they're meaningless. But because the rating is an "important" metric, app developers do so much to inflate it. All those annoying, incessant popups to "rate your experience", that, if you give 5 starts, would plead you to also rate the app in the store. As an Android app developer, I also have complaints about this — people would sometimes leave negative reviews because of something your app is not related to. Like "I used this app and my account got hacked", on the official app for the service that hosts the account in question.

And another tangential issue is how search in Google Play is a ridiculous mess lately. It would show you WhatsApp and some other popular apps for literally any search query, while not finding the app you're actually looking for, even if you enter its exact name.
