I have managed projects on about a dozen pre-release gaming systems. I can assure you that Apple's requirements are in line with those of other companies. Sure they sound draconian, but actually they are not too hard to follow. We've even had a situation where we had to create a walled off area at one of our developers and add a keycard lock. It's just what you do to be first to market on a new platform - a competitive advantage in terms of early adoption and gaining expertise ahead of our competitors in the same space.
Let me give you one other angle on this: I like the security measures. They force us to limit access to those team members who really need the information and visibility. And they heighten the importance of keeping our parters' intellectual property secret. In no way do I want to get a call from our legal department worried we were the cause of a leak.
We've even had to put in security measures for pre-release music. On Guitar Hero, we released a Metallica album as downloadable content day-and-date with the physical CD. So, we needed the tracks about 2 months ahead of time to program and test them with the game. Our quality assurance department was required to install metal detectors and confiscate any cell phones from the testers so that no one could copy the music and leak it.
