Nice to see a fair discussion about this subject. BB10 also has its shortcomings (like the inability to turn off Blackberry Messenger) but is surely a more mature OS - and a very nice one too. Having used it for a few days, I might get one as a secondary device to my Jolla one day (hardware keyboards rock ), but I still prefer openness, so I'd choose Linux distro over BB10 every time (note that I'm not considering Android a Linux distro) . But I totally respect people that have different priorities.

Why I joined the discussion:
Just to fix this...

LGPL doesn't seem closed to me, not sure where this misconception is coming from.
