A quick question for this part of your mail; I'm getting on thin ice with it (hope I won't regret this), but I guess it's worth it to make me understand the problem better: How is having a CC-BY text that tracks in part from GPL2 text or code in this case any different than having MIT code that links or includes GPLv2 licensed code? Both CC-BY and MIT are compatible to the GPL (see [1]) and the processed result is only available under GPL (see [2]).
