<p>Please notice that the number of upvotes does not need to be a good measure of the quality of a question, or an answer. In this case, the answer is just a quote and a reference. I guess that it got so many upvotes because people upvoted it to say "I agree that the question is wrong", rather then to reward it for an exceptional quality.</p>
