One priceless --and temperately phrased-- quote from Mr. Graham: "It is really hard to make money off of stuff when you teach people it has no value other than attribution, hugs, and hi-fives for how open we all are now."
And the bottom line: "The creative class of artists is teetering on the bring of utter collapse, and they want us to fund a study based on something they should have researched years ago. It makes me angry.
And you should be angry too."
I heartily recommend that you read the full rant.
Best wishes,
