Is this license open source?

[David Starner]

I've been thinking about a license I've been tempted to use:

This program is under the GPL, v2. You may also use it under the XFree
license as long as you aren't Theo de Raadt or Tom Christianson. *

I would guess that it's non-free, which leads me to the weird conclusion
that adding further permissions to a free license can make it non-free.

* Yes, I've stopped reading gnu.misc.discuss. And I'm better now. Mostly.
