Except what choice did he have? There was such a backlash against the current proposal, he almost had to throw them out, or face a massive revolt, via people voting with their feet and walking away. QT's proposal, on the other hand, was widely accepted and is a good stop gap to appease people, at least till he can cook up his own rules to replace them.
He wants to show that he really wants to change things? Repeal the permabans. Dump Shal, CJ, Corwin, and the other shitheads that are on staff, and put new people in that have a brain in their heads. That will make me believe that he's going to get it right this time.
