The GPL License is incompatible with many application-distribution-systems, like the Mac App Store, and certain other software distribution platforms (on smartphones as well as PCs). The problem lies in the right "To make a copy for your neighbour", as this right is violated by the integrated DRM-Systems made to prevent copying of paid software.

That may be the FSF's line, but it is not correct.

Nothing restricts you from putting your app in the Mac App Store and also distributing it in other ways (e.g. from your own web site) without DRM. Many apps do this e.g. BBEdit

Nothing restricts you from making the source code of a Mac App Store app available, which also preserves the "free as in speech" demands of the GPL. Anyone is free to get a developer subscription and xCode and compile the source code themselves. (applies also to iOS app store).
