I cannot stand people using auto-tune that worked on a song that's name is Death of Autotune. Then you should not be using it in future either. Hyprocrits.
Either way, I don't mind it as long as it fits. If you can sing your **** live, then you can have auto-tune.
If you can't, then you shouldn't use it either
Actually you shouldn't sing at all if you can't sing live.
