I'm not sure how it was controversial. Why did they need to show that part that said 'no goal'? I don't think anyone was ever in doubt when it came off the upright that it was not a goal.
I'm actually surprised that they showed that on the big screen considering they never show replays of 'big decisions' at the ground.
FIFA have said the first 'no goal' was to show that Benzema didn't score it, but that it was only a 'goal' once the keeper tipped it in.
