Is it Neffenger or the spokes-folks who don't know what's happening at the checkpoints?

Or is there some subtler purpose to the on-going announcements about the various imminent curtailments of 'free Pre'?

Is this just a big test? Some airports rarely offer Pre, some airports offer only Pre Lite, and some airports hand out free Pre for any number of reasons? Then compare Red Team test results to see what produces the best results?
