So Matt needs to stop posting and start filing.

Derivative software, unlike, say, derivatives of books, plays, or music, is not very well defined. Part of the reason is the lack of case law; the other part, sadly, is the ignorance of judges.

(IANAL, I just play one on the Interwebz.)

No, if it goes that route then anything written in Python, Perl, PHP, Rexx, and including our friend LUA – all have to follow the interpreter’s license. Ain’t gonna happen. All other arguments aside, that’s the way it is.

A fairly cogent argument is made here, and Mullenweg even has an opinion from the Software Freedom Law Institute (sounds pretty impressive, but I’ve no idea of this organization’s bona fides).

Only an experienced PHP code monkey would know for sure, of course, but as I understand it, Thesis is just a theme. In that respect, it is to WP as a script file is to, say, Python.

Python is an open source programming language. Programs are “script” files (uncompiled text files) that do nothing until run through an interpreter (python.exe on Windows).

I can create script files and sell them, close-source them via obfuscation programs, etc, and not violate the license that comes with Python. My script files are MINE, and I can distribute them however I wish. This has been made abundantly clear by many people, including the Grand Poobah himself, Guido Whom We All Adore.

So, from the cheap seats, I really think Thesis, and yourself, are OK with respect to the GPL.

And yeah the rhetoric from open source and gpl freaks is pretty toxic at times. I suggest not reading those fora or whatever for a few months and let them move on to the next bright and shiny object.
