Of course, they do care about profits, but it isn't their only agenda. This is why Google owning the patents isn't a major deal. There is no history of using the patents to get rid of competitors or to make a quick buck. They pull them out of the closet to defend themselves from other patent lawsuits. I am certain that if Google started going after various companies over mundane patents, the view of them will change very quickly and you wouldn't see very many people defending them.
