Agreed, but the ethics of some carriers, apart from Monarch, in doing such things are alive and well, and part of the day to day commercial realities - look at one of the two largest low cost operators in Europe, and not necessarily the UK owned one.
Tour operators aren't immune today either.
Fortunately not everyone sit there gawping at Facebook all day long - it's when consumer "jounalists" get their teeth into the airline the real danger arises - and I'm sure some of them lurk on these forums.
