I hate to bring this up, but this is perhaps one of the clearest examples of PR copy as mentioned by Paul Graham's Submarine post: http://www.paulgraham.com/submarine.html
Basically, this is a big advert for Yondr (the company making the phone baggies) - the clickbait title, the picture of the baggies, the quote from the fan saying he's ok with the whole thing, the list of artists signed up with Yondr, and the whole spiel about why a "phone-less" concert is such a great thing.
