I am also puzzled that you don’t seem to recognize the value in a name trademark from a defamation point of view. Palin, and rightly so, has no vested interest in financing those who would defame her by using her name in defamatory contexts. But as a public figure, she is hobbled on direct defamation claims. However, when her rights in her name are violated by her detractors, although their aim may be defamation, she now has a cause of action to use as an incentive to stop the defamation. Famous people do that, and it is smart, and is no predictor of pecuniary motive. It only shows that a person has an interest in protecting their own good name and reputation. For evidence of other, more sinister motives, you would need a crystal ball.
