I don't think they're trying to "crush" Samsung by extorting $15 per handset, I'd say they're trying to maximize their revenues by charging as much as they possibly can without triggering a lawsuit. If they wanted to crush Samsung, they'd insist that Samsung sell WP7 phones or nothing. If their patents hold up, that is their right.
