It seems to me that a military demonstration team that would use aircraft that are not in fleet service is very much like false advertising. After all, their main goals are recruiting and goodwill. A kid that joins the military thinking he can work on or fly (say an L-159) and then learns "Those are just for show, You'll never work on those." is a bait and switch.
So is getting him pumped about flying an F-16 and then handing him a cabin-crew assignment on a C-9 Nightingale. There's not necessarily a connection between "show" and "go".
Don't forget that a huge part of the PR and recruiting value comes not from the flash and noise of the flying, but the face-to-face contacts at the autograph line afterward. There the kids and parents meet pilots and crew and can ask about the reality instead of the theatrics. Demo teams are trained to explain the nitty-gritty of recruiting and careers - it's their job.
Once I learn how to shrink an .avi file I'll post a tidbit from a summer show with the Snowbirds.
