That citation is confirming their claim from the first sentence of http://en.wikipedia.org/wiki/Zynga#Intellectual_property http://en.wikipedia.org/wiki/Zynga#Intellectual_property that Zynga was indeed criticized on Hacker News. I'm not sure that's the same as calling HN a credible source, because they're not vouching for anything said here. In any case, it's interesting and I've never seen it before on Wikipedia. :)
