Every Airline I've flown for, certainly in the last decade, has had a strict "no photography" policy in security sensitive areas (e.g. the Flight Deck).
Many Pilots of course, do take photographs for their own personal collections. Usually of fascinating weather/landscapes etc looking OUTSIDE the Flight Deck rather than in it.
How these idiots are able to get away with such public profiles of inflight selfies is beyond me. Forget the bullying, why haven't they been fired for such blatant breaches of company policy?
