I don't think anything new is added to the discussion here. Not because it isn't a good article but because everything has been said a thousand times. As far as I can tell we are pretty much stuck because so much code has already been written with old licenses. It is becoming more and more alike to how W3C has become a standards body for Big Business and, what at least feels like, anti-user. A shared license might work but I'm not sure I would add any code to it.
In my opinion this is the old "Capitalism versus Communism" all over again. I know which one I prefer in theory and I know which one survives the meeting with human greed and they are not the same.
