For a project this big & complex, and for something that cost hundreds of millions of dollars to develop, 5 years is paltry. Duqu remained hidden for 11+ years.
If I wanted to own a machine and not be detected, that's where I'd live. It's also complex and closed source so you are basically guaranteed to have exploitable bugs that won't be fixed. It has access to network and system busses at a layer below the OS so ex-filtrating can be done at a layer below what the OS can see.
One good example from recent times of how well this type of "incentive" works is Google and Stagefright. The media went nuts over Stagefright affecting virtually all Android devices - and for good reason, too.
Since then Google seems to be taking Android security way more seriously, and there have been a lot of serious security improvements in Android (7.0) over the past year.
But these sort of actions seem to happen in slow motion, if at all, when there isn't a hacking/malware catastrophe for which the companies can get blamed in the press.
The NSA pushed hard for new surveillance laws such as CISA with the promise that it's what they need to keep us safe against cyberattacks. So why isn't every single media entity blaming the NSA over every major new data breach that happened since then?
If you want regulation, that's Congress and POTUS, not the NSA.
It doesn't seem as though this has been especially effective with regards to information security, however. There are just too many adversaries, it's too hard to project force against them, and there's not much of an effective deterrent effect by sitting on a 'stockpile' of vulnerabilities yourself.
But IMO the disconnect is almost a fundamental one, because it's an area where what has worked fairly well for the US for 60+ years is suddenly falling flat.
At this point I'd argue Google's security bounties have done more to secure the industry.
In terms of the "narrow scope" assertion: http://csrc.nist.gov/publications/PubsSPs.html
NIST seems like a good agency trying to do the right things. It's just that they're forced to work with bad actors.

"Department of Defence" is so PC, things were much more honest back when it it was called the "Department of War"
We honestly don't know. It might not even be the NSA.
