I don't think it's fair to make that kind of teleological evaluation... Yes, RapGenius may be the best solution for google's customer. However, if Google permits shady SEO tactics simply because the ends justify the means, then what kind of precedent are they establishing? They would be encouraging that kind of behavior. As a heavy RapGenius user, I'm upset with what occurred, but from an objective standpoint, it makes sense why Google made its decision.
