Some of us have also been bitten on the arse by non-free drivers before; somewhere in a cupboard I've got an old Sharp Zaurus that was rendered completely impossible to update by a single proprietary driver (for the SD card, of all things). It is a serious worry that Nokia plans to hand over maintenance of obsoleted releases to the community, but the community may not be able to maintain them.

People that don't care about this sort of stuff often claim that they're being pragmatic, but really they're blind optimists just hoping for the best. A pragmatist wants to make sure they don't get locked out of supporting their own device.
