Personally I just think it is a real shame that none of our cabin crew would behave during flight as depicted in these ads. If they did feel empowered and confident enough to do so then they really would make a great face for CX.
But the truth is that they are all super timid, all too scared of being reported or of being chastised by their colleagues. They run the cabin service like it is a race with little time to slow down and truly interact with the passengers. It would be a cold day in hell before three....THREE.....cabin crew gave a passenger a birthday card, or made eggs into a smiley face, or all the other fantasy world crap these ads depict. It's a shame, because if they did, it would make us a truly great airline to fly with. And it's a shame that the people who think up these ads are so delusional as to believe their own propaganda. But after seeing how they treat their staff I wouldn't expect anything else.
