What happens to an app when Apple pulls it from the store? The app remains on the devices that already downloaded it -- does this just prevent anyone from getting updates and any new users from downloading the coinbase app?
Right now, I'm connected with the Tether app - listed on the App store for less than a day, two years (and two iOS cycles) ago. So once you've downloaded an app, Apple does not generally disable it, even if they no longer approve.
> or remote uninstall on every device (generally used for malware)
Has Apple ever done this or said they could?
Technically, it would obviously be possible, but I don't remember Apple doing it.
My understanding is that when an app is pulled, it's usually still available for download if you had already bought it; but they have removed even that ability in a few cases.
