The additional clause (yes, the one you are calling an "interpretation") you are adding to the GPL (or, more recently, the CDDL) is so utterly non-free that it doesn't even need to be discussed. I'm very well informed on this matter, and I won't be corrected by people trying to retroactively change their (formerly free) licensing scheme when it comes to discussing about free software. -- .''`.
