Nokia tries *a lot*. Ask hardware vendors.

There is a good discussion about this somewhere in this thread...

Basically, Nokia puts considerable effort pushing hardware vendors in that direction. Open source drivers play well with the Nokia chipset strategy and with Linux development. But of course these companies need to make business, so asking them to open their IPR without suggesting any alternative is not the best approach.

MeeGo, with Intel as initial founder (a company with good track offering open drivers), is one of the biggest and most concrete public actions Nokia could push in that direction.
