But it's a co-branding strategy with a company that is widely condemned as having some horrible (and illegal) practices.
It's trivially easy to find these. I cannot believe that anyone at the largest search engine company in history failed to find or read criticism of Nestle before announcing the co branding.
The only conclusion to draw is that Google knew about, and did not care about, the criticism of Nestle.
Why not go the easy route and find a less obviously evil company?
Another possible conclusion is that they selected a few possibilities, including other K-desserts (Kakao? no, too Cocoa; Kremlin Cake? too sovietic; Kaki jam? Weird, too Chinese; etc) and decided the less bad one was Kitkat.
I'd say the problem is to be too systematic. Same with Ubuntu Zoomy Zoo and Apple iSeries. Would a writer submit himself to such a gimmick for his book's names?
However, my main grip again Kitkat would be that it is the same as all other "chocolate" bar: it is industrial junk-food, making us all obese, and it do not contain chocolate.
Cal Murphy (by Jack Patterson) uses Cross in the title - "Cross Hairs", "Cross the Line", "Triple Cross". (http://www.amazon.co.uk/Jack-Patterson/e/B0098F2E48/ref=ntt_...) (This last one feels odd - the author name is close to James Paterson, and the series titling uses a word ('cross') that happens to be the name of the James Paterson protagonist.
