Im a fan of both the Kaiser Chiefs and Mika. I think its the same with every artist you either love or hate them. Mika brings an energy to the stage and to his performance and puts on a good show, i guess if your into indie bands like the Kaisers then most people dont have the diversity to reach out to mikas type of music.... its all a case of tastes. if you like someone you praise them, if your not a fan then you all-out slate them.
in regard to that kaiser chiefs article (the one linked) i dont think anything too bad was said... kaisers just want their (first??) number one!
