It may well be analogous to that (though I disagree), but the quote does not
substantiate why knowing public information is bad. In the example above,
you've simply saved your switchboard and the caller some time. If you don't
want someone to know it, don't make it public (at the very least).
You'll have to accept that no matter what steps you take, your public
information will be available to those who wish to find it. Taking steps to
prevent that is likely to waste more of your time than it will of those
