I’ve gone to several comedy shows (5 or so?) that use the Yondr bags, and honestly I think they’re a pretty good solution. I think it’s fair for artists and comedians to want to prevent filming, and the phone jail thing is quite clever, actually. The bags are not indestructible, it seems like a sharp pair of scissors or a knife would get you in. And I think the magnet lock is actually bypassable otherwise. It’s just inconvenient enough that everyone pretty much just complies, while retaining physical possession of their phone. I kinda like the experience as an audience member, I think the phone thing does keep the audience more engaged with the show. I’m open to arguments against, but as it stands I find the phone jail charming
