It's complicated :) After Qt 5.6 some important parts were relicensed as GPL. Which means that the Wayland compositor and some other Jolla parts needs to be either GPL (which the main investor is reluctant to do) or Jolla needs to buy a commercial license for Qt (which the main investor is reluctant to do). I understand that the developers at Jolla are ready to flip the switch to a newer Qt and have been for some time, but there is no business decision made yet.
