the real reason
I work a lot with public-facing entertainers outside of the music industry and they too went through a phase of "please don't put it on youtube". They didn't want everyone to be completely familiar with their act when they do it again next time somewhere else.
As I say it was a phase and has now largely gone away - firstly they know it is a lost cause and secondly they found the exposure was beneficial and didn't impact future audiences.
Not disagreeing that people with cameras during the actual performance are very annoying.
