What's wrong with shipping GPLv3 code? Can't they just provide the source (are they making significant changes that they want to keep proprietary?) to comply with the license?
Apple likes to push DRM, which GPLv3 forbids. Apple also is afraid to give patent grants, which GPLv3 requires. Thus, Apple refuses to get anywhere near GPLv3 code, and won't even make it easy to give you GPLv3 source that you can build yourself.
