I have a buddy who's an old Apple QA who tells me similar jaw dropping stories about the silos and secrecy. When I marvel how they can possibly ship all those wonderful products he says it's done through grueling brute force manual QA testing. Which also sounds insane but somehow it has mostly worked through the years. But maybe they're reaching the level of complexity where brute force manual testing is not scaling well enough.
