I guess stills images are all filled with useless garbage then? Because those are 1:1.
Try doing debayering that good 24 times a second for half an hour. And then crop 2MP out of your 20MP still and see what you think of the quality. They have OLPF's for this problem, but they are a tradeoff.
Did Canon solve this problem in the 70D? I wasn't able to find chart tests. Too many morons trying to review video cameras using brick walls and the like, having no idea how moire forms (moire can also form from poor downsampling, but false color is a debayering problem) much less how to test it. Anyway it's of passing interest; I'm trying to cut Canon some slack here which is unduly generous.
