It could maybe be described as hidden in plain sight. If you dug around there were pieces in the public domain that you could put together. But if you suggested this, you would have been dismissed as a tinfoil hatter by most people. More to the point, the fact that it is a huge story in the news across the world proves that most people were simply unaware. So it doesn't mean much to say that this was already known when to most it wasn't. That could be taken to imply that there is nothing to see here and that people who are bringing it up are a little slow - which is simply disingenuous. The fact that my mother doesn't read every page of every newspaper doesn't mean she should be disenfranchised. And it also doesn't change the fact that many businesses are only now changing their behaviour and moving away from US companies and reconsidering architecture for IT projects and business operations.
