I can assure you that legal teams in studios are just as aware as those in the tech field, even with the (for the most part) distinct lack of apparent software distribution. Even if it's just for internal consumption, legal likes to know what's going on and where it might impact them later. However, the GPL and other copyleft software will not for the most part have much of an effect on studios unless they sharing some of their IP they've created with the broader community, partners, and/or proprietary software vendors.
