I don't care. I really don't. I don't get how it bugs so many people considering 99% of the time it's used you're either not going to notice, or it will make the song better. If they are enhanced to the point of sounding like robots, then they're doubtlessly doing it that way for a reason, and you would probably like them even less if they weren't using it. I don't know, but to me it just sounds like people complaining about genres of music they don't like to listen to anyway.
Then again, I listen to dance and electronica, and voice effects like this have been used to enhance those songs for effect for ages. I think those songs would sound wrong if they weren't electronically enhanced, so that might have skewed my perspective a little.
