They are dying because of lack of interest and as you well know Maemo may well be a great interest to you and me but where are the developers?. This WP could well spell the end of interest from the developers point of view in that there is nothing left to develop Maemo or Meego for so where we go now???.
The absurd thing is the community was trying to develop into a closed source OS ie Maemo on the N900. Where is the point in that? it had to come to a sticky end eventually and i am suprised nobody thought of this when they started Maemo.org in the first place. Maybe many promises were broken from the Nokia stable !.
