http://codex.wordpress.org/GPL [codex.wordpress.org]:

The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. ... Activities other than copying, distribution and modification are not covered by this License; they are outside its scope.

unless thesis is distribute with a copy of wordpress and/or unless thesis contains wordpress source code or a modified version of wordpress source code, then matt is dead wrong and GPL does not apply.
case closed, end of story.

Matt's position: the license is clear and if you want to extend WP...

nowhere in that license are extensions addressed - plugins, themes or otherwise.
