Because I think, given the government's reaction to it, we are headed for years of further reports and submissions and committees and, in the end, nothing much will change.
Moon essentially endorses the CHRC's choices in selecting and pursuing section 13 cases. In fact, he suggests tweaking criminal code provisions such that all of the cases successfully prosecuted under section 13 would also be captured under the new regime that he has proposed. So while you can argue that using the CC for such work is inefficient, and you can argue that the odds of provincial police forces actually setting up "hate teams" is Nil, nothing in Moon's proposals would, in theory, let anyone who has already had a run-in with the CHRC off the hook.
What would happen is that complaints dealing with the kind of material now handled by the CHRC under section 13 would go to the various police hate crimes units (whose workload, Moon suggests, would almost certainly increase). So, while nowadays Connie and Mark, or Mr. Boisson, might get a letter from a government bureaucrat, under the new regime they would most likely get a call from a nice policeman, and this would occur just as their websites (via section 320.1 of the CC) disappeared until said policeman could decide whether its contents met the standard. Since Freedominion occasionally hosts calls for Muslim genocide in its forums, it is almost certain that they would be getting such phone-calls, and might wind up looking at jail-time rather than a fine and rebuke.
How that is supposed to be an improvement, I do not know.
