Kotaku gets away with it too. However, I've long maintained them to be the worst site on the Internet.
I really think it all shakes down to how they USE the review. Meta-reviews, short excerpt to illustrate a point (when properly cited), are fine. I think it's especially constructive if they use multiple sources. However, doing that essentially shuts you out as "professional." It's a blanket admission that "our opinion isn't really all that worth noting."
Just long paragraph excerpts for no point other than to create an article and register hits is another thing all together...
