content: I don't own a cellphone, and I'm completely oblivious to how they've changed human interaction in the last 10 years.  I know you're young, introverted, and being paid to post by the UK government, but there's this thing called "Art" that used to be praised equally or moreso than "Profit". It might blow your mind a little, but there are people that exist that aren't motivated by money once they have enough to be comfortable. These people tend to stop performing when the money outweighs the crowd engagement. In order to keep these people motivated, you have to maximize the amount of attention the crowd is paying them.  Slaves demand/require regulations, otherwise they'd be free people. Cellphones have changed the slaves irreparably in the eyes of performers. Therefore, performers are trying to flex the little power they have to keep their experience untainted by the slaves they need, lest they get demotivated to perform.
