That implies Google has some data to back it up, whether they themselves previously asked those types of questions, or they derived it from some other means. Either way, they aren't doing themselves any favors to dispel that urban legend. Most reading that will just assume they used to ask brainteasers, but no longer.
Yes, it's a rather strange objection to make... How could Google possibly use data on its employees to disprove that brainteasers work - if they weren't using brainteasers at some point?
