Keith,

Any statement can be made foolish if you tweak the words a little.
They said, "Unmaintained systems become more vulnerable with time," a
reasonable and possibly correct claim. You paraphrased it as,
"unmaintained systems develop more
vulnerabilities with time," which is, of course, absurd.

The vulnerabilities were there the whole time, but the progression of
discovery and dissemination of knowledge about those vulnerabilities
makes the systems more vulnerable. The systems are more vulnerable
because the rest of the world has learned more about how those systems
may be successfully attacked.

Regards,
Bill Herrin
