Have you not realised yet that you're not the target audience for it? Just addressed this elsewhere before seeing this so some of this may be repeated thoughts.
It's something for the kids and tourists, there's really no reason to be upset with it if it's not for you. If it wasnt there, they'd be nothing, we don't lose anything by having the lightshow. You can still sing during it if you wish, Chelsea fans did, about the only time they bothered to sing. When the song changed to love will tear us apart, a loud rendition of tearing cockneys apart broke out, we would never get that loud of a rendition pre-match without the lights how guidance. It creates a louder atmosphere than nothing, it caters to a different audience and does no harm. I say well done City for bothering, they dont have to do anything and there's no reason whatsoever to be against it.
