That might very well be it - for example, the GPS does not work at all with Nemo on N9 and N950, due to a missing driver. According to the Nemo developers, this is unlikely to be ever fixed (IIRC what they said, the driver should have been opensourced originally, but this was killed by Elopocalipse). Also I think the drivers/hardware adaptation on N9 and N950 is licensed from Nokia under a non-commercial terms. This might also complicate things a but. Other possibilities:they don't want to alienate sales of their own device fear of some company slapping together a Sailfish phone before Jolla (IMHO unlikely) fear of indirect support costs (even if you tell people they are on your own, this does not mean they won't still spam you with questions per Email or on Twitter) Still, it is quite unfortunate, due to all the wasted potential - both for Sailfish application development and due to giving a new life the N9 device family.
