I work in the industry (QA consultant for a large company - we may or may not have been under scrupule recently DUE to a leak from one of our testers regarding a videogame). And you're damn right it aggravates me - people who do that at my place of work are often shunned, and when I hear of leaks from a project that I know is in-house, I can't help but to think maybe it's one of us and it makes me want to straight up rampage.
