Very interesting post. As it happens this was the subject of two talks in the FOSDEM Legal DevRoom, one by the FSF's John Sullivan and one by me. John ran a script on recent Debian releases and found that the proportion of packages licensed under GPL-family licenses since the release of GPLv3 was increasing, not decreasing. (My talk raised some doubts about Aslett's stats but I mainly used the topic as a prop to talk about why one would expect the GPL family to be in decline even if it isn't.)
