Yes the desktop environments are still using GPL but those are already established projects, not growth areas. For newer projects it seems there is a shift away from copyleft towards Apache-style licensing. The newer copyleft licenses (GPL3, AGPL) just haven't gotten that good of a reception. And in the areas I've seen that do use them it seems it's despite the FSF, not because of them, for example the FSF seems to have completely given up on license enforcement or helping with anything in that area.
