It's because Apple have either intentionally turned a blind eye to these companies or they have managed to sneak it past the app store review team. https://developer.apple.com/app-store/review/guidelines/ https://developer.apple.com/app-store/review/guidelines/ Section 3.1.1 In-App Purchase: If you want to unlock features or functionality within your app, (by way of example: subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use in-app purchase. Apps may not use their own mechanisms to unlock content or functionality, such as license keys, augmented reality markers, QR codes, etc. Apps and their metadata may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase. So you're actually proving the point that their review system is neither fair nor consistent with your crusade in here. Also don't forget about survivorship bias. For every app you see that does this thousands of others got forced to use IAP during the review process.
