Nah, just having some fun
Seriously: it disturbs me more in museums than in concerts, though professional photographers in concerts can be a very obnoxious bunch (and having the entire thing filmed by various cameras - and even better if they drench the whole darned stage into blue light for later TV presentation - is a major nuisance and should be announced beforehand, since I would very likely not attend any such concert).
I guess we're in the age where it does not count what you know and what you actually have done and seen in your life - rather it's all about "I know where I can find any information (not knowledge, mind me!) at any given time at any given place in orbit" and about "look world, I've been there, ain't I cool?" - the photo-mania to me is but an expression of that mentality, which is very alien to me.
