Worst part is once you learn what the Vocal Fry sounds like, you will start hear it literally everywhere. At best, it was interesting to recognize in the real world; at worst, it ruined some podcast hosts for me.
Try singing it like he does, fry and all. It's fun and sounds pretty good.
I don't think it has anything to do with some vague notion of "hate".
Some people simply find it to be a distracting phenomenon that can make it harder to understand what somebody else is saying, even when they like the speaker.
