But isn't it as clear as the nose on my face that this delay shows that the aircraft did not have a gate assigned - even a remote stand - and therefore the passengers could not leave the aircraft because of the lack of steps (although I know the 738 has front steps built into the a/c!).
Therefore the passenger is liable for personal injury - getting off the wing - and to any aircraft taxying or other airport vehicles in motion .... plus time and costs of refitting the emergency exit.
Whatever the 'reasons' (or lack of them) were or the passenger's personal situation, he should not be 'rewarded' by 'social media fame' and should be shamed and made to pay for the damage and inconvenience caused to other passengers on his flight. And being put on a 'no-fly' list seems quite a good measure as well.
