Bill Watterson, an artist who wouldn't merchandise his work despite heavy pressure and substantial enticements, and fought hard for having a real life:
"Selling out is usually more a matter of buying in. Sell out, and you're really buying into someone else's system of values, rules and rewards. The so-called "opportunity" I faced would have meant giving up my individual voice for that of a money-grubbing corporation. It would have meant my purpose in writing was to sell things, not say things. My pride in craft would be sacrificed to the efficiency of mass production and the work of assistants. Authorship would become committee decision. Creativity would become work for pay. Art would turn into commerce. In short, money was supposed to supply all the meaning I'd need. What the syndicate wanted to do, in other words, was turn my comic strip into everything calculated, empty and robotic that I hated about my old job. They would turn my characters into television hucksters and T-shirt sloganeers and deprive me of characters that actually expressed my own thoughts."
The above, quoted by Nevin Martell in his unauthorized biography of Bill Watterson, Looking for Calvin and Hobbes. I almost included two paragraphs of rather pointed analysis of said book but Upon Reflection, I'm not sure those thoughts are worth airing. I'll just say, "Hear, hear!" to Watterson's words.
