Just to clarify copyright vs license: The creator always has the copyright on what I've created, and it's him/her who decides how weak or strong the license for other people is. It's his/her decision only as he/she created it, no matter whether it's music, books or software code.
Pushing the creator (e.g. me) into using a specific licence means reducing my personal freedom and pushing me into something ideological. And “Ideology is a brain disease,” to quote Jerry Rubin. Hence I'm happy that there are different licenses available, from weak to strong, and that the creator (Nokia, you, me, whoever) can choose.

I respect the creator's decision and can of coutrse question it.
If good arguments are provided creators revise their decisions. For example Carsten filed requests with very good arguments in Bugzilla to open the code of example statusbar-alarm-dbus-api (#4560). Hence Nokia has changed that code to open source.
That's how it works, and I like it.
