People knew the rules ahead of time, and they weren't rioting in the streets. In fact, nobody complained until after Carlsen won, when all of a sudden it is a great injustice.
Is it really that hard to understand that all the players knew the rules ahead of time, and none of them publicly complained? Nor did any of you whiners start complaining until you didn't like the tournament results.
Making up new arbitrary rules along the way to please some kibitzers in Internet forums is an excellent idea. In case of a tiebreak there should be a cooking contest between the final two contenders. This year's theme could be curry, in honor of the incumbent WC.
