It's almost certainly someone's (er, snow's) specific job/duty to police the forums daily. No need for discussion or permission to do so from upper management. However, posting release notes likely requries permission to do so and/or discussion with a larger team (writing, fact checking, vetting, posting). I doubt one person fills all of those roles. I'm troubled by our collective implied consensus that it's okay to be slow in responding to requests for the SDK but not in responding to questions on the forum. Double standard there?

That said, it just seems remiss not to post release notes for software that's already been released.
