That seems like bad advice to me. A possible infinite loop is given as justification in case of wrongly implemented reverse iteration (counting down an unsigned loop variable). Well, i claim that an infinite loop is a much more noticeable bug than undefined overflow behaviour, negative view counts, etc. Unsigned ints will make bugs impossible that with signed ints will (hopefully, famous last words) trigger assertions, if they are enabled...
