SecurityFocus interviews Ron Gula to get a glimpse of Tenable's upcoming free (but closed-source) Nessus 3 vulnerability scanner. The discussion looks at license changes, community involvement, daemon security, new features, GPL open-source versus free, NASL, and more.

Implied in response: There are people in our user base who can't abide by the GPL, therefore we have to stop licensing under GPL to satisfy them.
Truth in fact: If you own the IP, you can license it one way, ten ways, or a million ways; There is no need to stop distributing under the GPL in order to distribute under another license.
If the concern "was to have a better relationship with our user base" there was a very simple way to do this: Offer them the same stuff under a different license. (In exactly the same way a music company will license a song via CD differently than they'll license the exact same song for use in a movie.)
Removing the GPL distribution does the opposite of having a better relationship with the (GPL using) user base.
Prediction: Nessus 2 will be forked. After community development, it will overshadow Nessus 3. This will provide another reason to switch to free software instead of closed/proprietary systems. Tenable will then be in the unfortunate business of supporting a security scanner a step behind the cutting edge, for a decreasing market of proprietary vendors; all while watching the IP they _could_ have GPLed and other-licensed slip completely out of their control.
But hey, they will have gained "a better relationship with [their] user base"; all three users are sure to appreciate it. Thanks Tenable!
