While that might be good for Nokia (I am not personally convinced), it brings nothing to the consumers except another shiny vehicle for Google's OS.

Even with being open-source Android is almost impossible to use securely and privately. From Google to every minor app developer everyone is trying to syphon data. One can install CM, but the permission system is still broken and the moment you install gapps over it one cannot even save contacts locally any more. I could go on, but my conclusion was that it's not worth the bother to try and get Android to be more respectful of one's information, it is designed to do the opposite.

So, no thanks from me. The market needs fresh ideas, not the same semi-open OS with a nicer Nokia camera.
