Yeah, I didn't see the point in dual licensing between two FLOSS licenses in
jQuery's case as it was free software through either license and they weren't
forced to the rules of the GPL. Makes sense that they removed dual licensing
alltogether.
Oh and I meant to post these links earlier on the MPL as I found them
informative:
