This is a tough one for me, because I am of the mind that we must all adapt to the new realities of the information age we live in; realities that come with major benefits as well as major downsides.

For one, I have benefited from fans using their cell phones to live stream shows on Hoodstream.

However, this trend disturbs me. I think the OP correctly characterizes this debate as an ethical one and I believe recording someone who is peacefully pursuing happiness and posting it on the internet is unethical. Or, to put it more precisely, this is a "dick move".

Sure, it's legal. It's not illegal to be a total asshole. But I don't want complete strangers posting videos of me on YouTube. Whether I'm drinking a cup of coffee at Blue Bottle, playing at the park with my kids or enjoying a psychedelic experience at Phish.

@RunawayJim: I completely relate to the experience of being around fans who have taken way too many drugs and are ruining the experience for others. For those fans, I see having their terrible behavior posted on the Internet as a type of justice. But I think you'll agree that the type of behavior we're talking about is not of this nature.
