As they say in politics, "follow the money".  Here it's the same thing.
If you look up the names of those who were outraged at Amanda PL (the artist whose exhibit was cancelled)  you will find some really uninspiring artists whose own art careers are - well let's just say less-than-thriving.
Meantime, the usual suspects of artists and advocates who stand to make a buck by associating themselves with the aboriginal industry will, predictably, come out of the woodwork in order to promote their own viewpoint.  I'm sure every single aboriginal academic will be clamouring for a $100,000 grant so they can "study this complex issue"...no doubt because of the immense public benefit of being able to go on CBC afterwards and talk about it (again, more self-promotion).
