I can't speak for the others, but the Vancouver logo was representative of a totem as a fair bit of the brand of the Vancouver Olympics was celebrating various Canadian native communities.

I think the real upset is that the others are simple, but professional. IMO this one looks more like a bunch of cut out pieces of construction paper or a little more like grunge/graffiti. Maybe I'm missing a deeper meaning to the logo, but I think that a lot of people are if there is one.
