Maybe we both have different visions of what openness means, but to my view, Nokia is really commited to it. They have been founding development of some open technologies I'm using on my computer right now such as gstreamer, telepahty or the Linux kernel, but they do it mainly through another companies like collabora. Now, they have buy Trolltech and are pushing Qt. I think we're never going to know exactly how much work is doing Nokia on some open source projects, but what I have for sure is that buying those devices is helping to have a much better open source ecosystem.
