An interesting point is GPL vs LGPL vs Some BSD/Apache/... licenses.

GPL for Maemo can work like it did for Qt and force competitors using your platform to only produce GPL apps and thus opening all their work to you because you control the API. The LGPL wouldn't give that advantage when you own all the source and can dual license to yourself.

Android though went in the other direction and used the Apache license which will allow carriers to embrace and extend Android, locking it down however they see fit for their own profit disregarding any previous contribution whatsoever. This will just create more apple-like lock-down in various carriers market.

Which for me is the worst of both world in a made to be expanded platform ...
