The problems are with software that ships from the Apple App Store,  
due to the way that is managed and the Terms of Service. It is the  
management and terms of service of the App Store that conflict with  
the GPL/LGPL.  Apple ships lots of GPL and LGPL software as part of  
Mac OS X and iOS, but that does not touch the Apple App Store, so they  
can be in complete compliance.

So Max, if you are interested in the Apple App Store, I think it is  
incompatible with all FSF licenses, and perhaps all copyleft  
licenses.  The short term answer is to ship your iOS apps outside of  
the App Store, and the real fix is to get Apple to make their App  
Store compatible with copyleft licenses.
