Specifics are hard to come by, perhaps it was a presentation or IRC revelations. Either way, search is no longer optimized for finding info for non-consumption results and Apple is accomplished at forcing NDAs and hiding specifics behind vague legalese... until circumstances arise that can no longer be vehemently denied and the flowery marketing speak flows: they seem to address the specific concerns without actually being definitive. Oh yeah, they often promise not to do questionable tasks, like accidentally tracking all iphones for over a year, too.
