This doesn't seem to be getting a lot of play, but isn't it important to note that YouTube has been generating ad revenue by serving this content to this audience? It seems like they are only stopping this practice because the amount of revenue that they will lose from Nestle, Disney, etc. exceeds whatever amount of revenue they had been generating by aggregating these videos and serving them to this specific audience. Preventing the aggregation and serving of this class of content seems like the larger problem. It's also not clear to me if the removal of the comments will prevent the aggregation of these videos. My suspicion is that even with the comments removed, these videos will still be grouped together and will still garner the same undesirable audience. I don't see any talk of somehow clearing whatever history Google has collected that has caused them to be clumped together in the sidebar.
