I've heard it explained that "hey" used to be more of an urgent way to get someone's attention, rather than a casual "hello" like it is now, so it sounded rude to some older folks.
Indeed, every elder phone should have a shortcut to the Urban Dictionary.
Many don’t agree with words that have been accepted into Oxford or other dictionaries. So the sarcasm falls flat.
