Or do you just have a personal distaste for them?
i think it is a drag on the viewing experience. (makes it a less good viewing experience). which in turn will decrease the views. and if you realize how much the ads are targetting you, it can be quite creepy and offensive, depending on if you are aware to the extent you are being targetted. and if it's the same ad every time, then it can be insanely annoying, depending on your level of annoyance tolerance. but regardless it is a waste of the viewer's time, and will cause many viewers to exit, understandably so, in order to not have their time wasted
