They aren't making 'extensions' to GPL code but merely linking *to* the GPL'd code from their 'closed domain'. They would also (presumably) take into account this *linking* when distributing their code to 'contracting shops and other third parties'. Basically, if you want to distribute code (in any form) then it isn't such a good idea to link to a GPL'd library because then you can't control what the third party does with the code. Using the GPL for a library is designed to be this way (not discussing 'should' here, that's just the fact of the matter) which is probably why the big studios tend to use a more open license when releasing their internal code. I'm going to go out on a limb here and say that the very fact that studios are using FOSS code *now* means that there are systems in place to ensure that non-open code doesn't get released into The Wild and any shop that doesn't implement such safeguards are just asking for trouble. Plus this is the pretty much what Ton wrote but I love to point out the obvious. Of course this doesn't in any way address the proprietary extensions issue but then again neither was Ton.
