People complaining about autotune use are way over dramatic. Autotune is just an easy form of vocal modification. Every
recorded album, and many live albums use vocal modification.
Autotune is only bad when it is used to make up for a singer's lack of singing ability or laziness. If you listened to Aim and Ignite, obviously he can sing, very well at that. So he's using autotune now (or more likely, a vocoder). That doesn't mean he isn't talent or that he's lazy. It means he's experimenting with styles (not that I like how it sounds, at all).
Daft Punk has extremely autotuned vocals, never see anyone complain about that.
