Except that it's not obviously for security concerns. hey might want to make it difficult for passengers to record broken equipment that makes them look bad.

Except that it's not obviously for security concerns. hey might want to make it difficult for passengers to record broken equipment that makes them look bad. They might just be unhappy about the out-of-fashion decor. Or they might want to make it harder for competitors to build a complete record of their fittings. It might be as simple as not being able to tolerate a flash going off and making a blanket ban that covers all cameras is the simplest way to do that. There is any number of reasons why they might want to ban photos of plane equipment that just boil down to airline self-interest without playing the "security" card. Not that this invalidates them, but it does put the flight attendant's request in a less all-trumping context.
