Frank O'Connor, franchise development director at 343 Industries isn't a fan of insiders leaking confidential information on the internet. Leaks in general and Halo leaks in particular were discussed over on NeoGAF and O'Connor inserted himself in the discussion.
"Breaking embargos is not prophesy. Nor does it require any particular skill or insight. Ultimately he is taking or being given information and leaking it, illegally and often erroneously.
And he isn't doing it for some noble or worthy reason. He's doing it for attention.
People, including nice people with kids and families and stuff, work super hard on this stuff and wake up in the morning to find some of their effort blown up.
It's not fun, and for what? So you can have a mildly interesting surprise 8 hours early and lacking context? Or get hyped or disappointed disproportionately?
Or get someone fired or someone innocent yelled at?
Ok. But it isn't prophecy, nor ultimately even important. It's annoying."
Clearly embargo leaks can be a problem. Especially as the information risks getting distorted (the one leaking it is often not a direct source of the information). Then again, if you're working on something people deem worthy of leaking you are sort of blessed in a way, so it's not all bad.
