Why do people hate on KHAN's new fighting style?

Was he a bit more exciting before the Collazo fight, sure. Even in the Collazo fight it was far from boring in my opinion. He did clinch and hold a lot but was active when he didn't do those things and still put on a great performance. A trainer finally has got Khan to fight in a style to protect his chin which involes clinching and holding. I don't see how as a boxing fan you can hate on a fighter for trying to overcome his weakness by changing up his style of fighting. If Wlad never fought the way he's been fighting for so long perhaps he would have been KO'd a few more times before retiring with his suspect chin but instead he adpated to a style which helps prolong his career and gives opponents less chance of KO'ing him. Inb4 the usual low IQ sub humans on this forum that can't comprehend what I've written.
