Whatever happened to the half-life of vulnerabilities?

From
https://community.qualys.com/blogs/laws-of-vulnerabilities/2015/01/27/the-ghost-vulnerability
:

"Where can I download the exploit?

We want to give everyone enough time to patch. According to our data once
the vulnerability has reached its half-life we will release the exploit.
Half-life is the time interval measuring a reduction of a vulnerability’s
occurrence by half. Over time, this metric shows how successful efforts
have been to eradicate vulnerability. A shorter half-life indicates faster
remediation. Half-life was originally coined by Qualys in the Laws of
Vulnerability."

Hello, it is July 23, 2015, 17:00 UTC, the Coordinated Release
Date for CVE-2015-3245 and CVE-2015-3246.  Please find our
advisory below, and our exploit attached.

*Why* are you releasing a full exploit just minutes after the patch
is released?

personal question.)

There was absolutely nothing wrong with Qualys' timing. When the
embargo ends, it ends.

The real problem is the underlying model: "responsible disclosure".
It's nothing more than a CYA strategy that doesn't maximize the
ecosystem's welfare. The positive-sounding name fools some into
thinking it a good thing.

Agreed. Coordinated disclosure is much more precise.

Also, it's judgment-free unlike the loaded term "responsible disclosure"
that implies alternative disclosure models like full disclosure are
irresponsible.
