CSSU has brought some good enhancements, *none* of which would have been possible without the vendor if all significant parts were closed. Sure, there are some things that can't be fixed, but the fact that my phone has a desktop that works in portrait (and many other pieces now work in portrait), that I can lock the desktop and launcher (so you don't accidentally move things around) and lots of other features, are because enough of it is open.

Have you tried current CSSU?

Remember that Meego is only doing *reference* UIs. The Nokia N900 people who have access to "ALL closed code" are doing hardware adaption, and the fact that a lot of N900 and other RX- device support is in mainline kernel is a testament to Nokia having done some things right.

I don't believe anyone at Nokia working on Meego had the mandate to open-source closed pieces of Fremantle or Harmattan. However, you keep basing all of Nokia's efforts on this single aspect, which was (AFAIK) never the plan.

You would have to be more particular about what you consider to be the OS. Some people wouldn't consider the default graphical shell on a consumer electronics device to necessarily be the OS, whereas others might.

You keep saying that, but the proof that is available in CSSU shows that even if a platform isn't 100% open, it is still possible to provide valuable improvements with those that are.
