Can someone explain to me why Rosie O'Donnell even cares about this now that she has left The View and has moved on to other things?

ABC released a statement saying that ratings for the show are up 16% since she left the show and Whoopi took over her spot. But Rosie questions those numbers on her blog (in a post titled TRUTH IN ADVERTISING BABY!!) and gives the "real deal" when it comes to the ratings. Her post is rather confusing, using lots of numbers and plus and minus symbols and percentages. She points out that younger viewers are down and older viewers are up, which isn't good for the show.
