Apple Approves, Then Removes In-App Ad Blocker (reuters.com)
Mickeycaskill writes: Apple has pulled a number of applications from the App Store, most notably the "Been Choice" ad blocker, because of concerns the methods they employ to rid adverts could compromise sensitive user data. iOS 9 allows for the installation of applications that block adverts in Safari, but other apps like Been Choice go one step further and let users remove adverts from applications – including Apple News. Been Choice routes traffic through a VPN to filter out adverts in some applications, but it this technique has attracted the attention of Apple, which is concerned user data could be exposed. Apple says it is working with developers to get their apps back up and Been is refining its application for resubmission. In any case, Been says users must opt-in for in-app ad blocking and that no data is stored on its servers.
Nope.
So far, if Apple even has the ability to uninstall an app, they've never used it. They've never used their ability to disable apps, either (though limited to ones which use CoreLocation, since the disabling code is in there, so if you never touch GPS...).
All Apple has done is basically prevent users from redownloading apps. But even that's not as big a limitation - you can still back up an app using iTunes. Or download the app using iTunes and install it via iTunes (recommended method for large apps). Even if the app is removed, as long as you have the IPA (the app file, similar to apk for Android) file somewhere, and iTunes is available, you can install it via iTunes. iTunes doesn't check - as long as the app is in your name and account, iTunes will install it on your device long after the developer has disappeared.
This was how users of a particular (medical) assistance app kept using it - after the developer has been sued by some larger company or patent violations that forced Apple to remove the app, the users backed up the app via iTunes and use that to install it on every new device.
The only thing is, it's unmaintained, so if it doesn't work with a new OS version...
And if you wanted, using iTunes you can back up old versions of apps too, so if they try to screw you or add stuff like ads or IAPs (in app purchase) you don't like, you can always revert by installing that particular version of the app.
