Revocable GPL (Groklaw)

The above mode of argument has a name.  It's called "begging the question".  At the core, its
pattern is "Assuming (1) I'm right, then (2) ... (n) therefore I'm right."  

You cannot reason about how the law will treat a license, a licensor, and licensees based
solely on the text of the license.  The law determines much of the meaning.  The copyright
holder has rights under the law that aren't stated in the license, and that may override what
is stated in the license.  That's the topic under discussion.  If you haven't got that far,
you haven't got anywhere.  

The problem is that the law isn't clear.  You can wish all you like that the law were both
clear and agreeable with your prejudice, but the facts are otherwise.
