It appears the NSA finally engaged in the Vulnerabilities Equity Process — not when it discovered the vulnerability, but rather when it became apparent the agency wouldn’t be able to prevent it from being released to the public. (…)

But when it was first deployed, some inside the agency felt the vulnerability might be too powerful to be left undisclosed.
