In what way is this less clear than forking out $199, investing time & effort and then discovering your application is not 'acceptable' for the Appstore ? The delineation between LGPL and commercial licenses is VERY clear. It's not the LGPL limiting your options, but the commercial extending them. With the Apple SDK you basically got what you roughly have (from a commercial viewpoint) with the LGPL, except you have to pay for it and don't get the source With the commercial license you actually adapt the framework to your needs - good luck with that in the Apple world
