to welcome visitors into the "office" is still perfectly fine in some jurisdictions, and for some operators, at the captains discretion. Properly briefed and safely strapped into a jumpseat, I don't see that as a risk to aviation. Letting visitors play with controls on a passenger flight is an entirely different thing though, for that, I do think the pilots deserved to get sacked. The added stupidity of mixing tits into it, and at the same time letting visitors document this with videos/photos is beyond belief (and yet it happens again and again). They may be excellent aviators in many ways, but lack judgement, common sense, and professionalism. "Do not inflate until you have left the aircraft" comes to my mind, regarding male pilots equipment...
