let's be honest here, shall we?
Maemo (MeeGo blabla...) never was profitable
N9 may have scratched it if it had been marketed aggressively enough, indeed, certainly with Nitdroid, but... how would that have looked, claiming they don't want to become another "Android OEM" maker and having (one of) their most successful device of the moment... mostly be used under Android
without Flop / Fart's burning hara-kiri NOKIA would have been able to go on supporting Maemo

the only reason Android is so successful is because it is so open.
the only reason i can be so open is because Google can afford to give it away.

again see opening remark, no way a startup will be able to sustain that business model.
period
end of discussion
end of dream...

open source is not a viable business model
never has been, never will be.
