There are a few things at play here. We live in a society where people are quick to broadcast how terrible others are, often without much self-reflection on why they feel so angry.
Take Chauncey, for example. He has dedicated himself to his craft, and through hard work, he has reached the highest level. Regardless of personal opinions on his approach, there should be some appreciation for what he has accomplished. It's easy to be bitter about someone else's success, but that's when self-reflection matters most.
On the other side, when so-called "fans" bash him in forums and on social media, it fuels negativity that spills into the arena, leading to boos. I don’t know about you, but I wouldn’t enjoy being on the receiving end of that.
There's a big difference between saying, "I don’t agree with his decisions," and "That guy is terrible."
