I remember Dennis Miller at the start of his slide toward loathsome spokesworm for the people that suck all the good out of life doing some bit about he worked with M&Ms because it meant money for him and for his family, so it was OK to sell out. His argument made sense, and I don't think anyone would begrudge a guy working with anthropomorphized candy for a payday. I'm not aware of M&Ms collaborating with the Nazis like IBM did, anyway.
Unfortunately he somehow decided working with the likes of Karl Rove was equivalent to working with M&Ms, which is a big insult to M&Ms. Yes, the pretzel M&Ms were a big mistake, and the commercials were juvenile and puerile, but overall M&Ms are an OK product that you can choose not to eat if you don't want to eat them.
