Since you're just getting downvoted, I may as well say that as a member of the press it isn't uncommon to see embargoes on stuff like this. They don't say a week out "hey we've got a huge security announcement" but they do say "we have something coming out this afternoon and we're doing a briefing half an hour before if you agree not to publish before we go public."
It's often in the interest of the reporter to agree to stuff like this since publishing security issues ahead of time can have serious negative consequences.
