Unsolicited weird opinion of the day:
I unabashedly love auto-tune.
I think its awesome as an instrument/effect itself on people's voices and adds another dimension to a recording studio as an instrument itself.
As a paying studio customer regularly I love when a the producer can fix a note with 2 clicks of a mouse instead of multiple people having to redo a Take when time is money. It liberates!
I can understand people thinking it's cheating/covering up absence of talent and whatnot.... but that happens in recording in hundreds of different ways.
For instance, On a recent record I played on one of the songs is 2 separate takes copy/pasted together half way through.
Or... many people don't even know who actually played an instrument on a record. Netflix documentary Hired Guns is incredible.
