The autotune you refer to as "janky and fake" is when autotune is used with intention to create that sound as an artistic syle. Autotune is used across most pop (and other) music, but in such a way that that you never realise it is there.
It is similar to special effects. People complain about how bad and fake they look, but this is only for the effects that are bad enough that they are noticible. People don't realise the sheer amount of special effects being used in scenes they never realise they are being used for.
