Turns out a complete non-story.
The reason doesn't make it a "non-story" in any way.
Nobody sane expected the reason to be anything besides something like that (e.g. some evil root access plan) -- and it's still a story.
The "story" here was that Apple was being irresponsible by giving Blizzard an exception to the sandbox.
In actuality it's little more than a shim to make a buggy Blizzard updater not crash by thinking it could do something it couldn't.
