People turned on Chris Jericho the person because he has become the very thing he used to speak out against when he was still in his prime, and still delivering great wrestling and elite character work.

He's the worn out, old-timer, blow hard who takes up screen time and thinks he is one of the greatest to ever do it(which is different to being one of the best to ever do it).

'We aren't booing you because of your effective heel work, we are booing you because you are simply awful' is what sums up Jericho now. He used to be great, but everyone else besides him has realised those days are long behind him.
