The FSF is saying that if the Apple Store wants to distribute a program covered by the GPL, they should comply with the GPL. Which seems reasonable.

If you wrote code 10 years ago under the GPL, you retain the copyright, and may distribute the code or the program how you please under whatever license you like. Other people do not hold the copyright, and may not distribute your program under licenses of their choosing. People and companies do dual-license fairly commonly, allowing the free software community to use and develop their product, while retaining the ability to license it commercially.

The FSF clearly does expect the software will be removed from the store, hence the linked communication. But they are not requiring it. This is somewhat more lenient than you might expect a commercial software vendor to be if their software was being illicitly distributed by Apple on the App Store.

Hope this helped clear things up for you.
