I don't think it's a poor analogy. We all can cite anecdotes of people being fed up with something, but it won't lead to its death. Your IT dept anecdote is just OP's "I know people that quit Facebook." Also, look at how people use Facebook. Quitting it would absolutely require a change in their social habits and opportunities. Too many HNers look at Facebook through the lens of their own slowing social life. Long out of university, aren't meeting people regularly. Yes, makes sense that you could delete Facebook with a skip and a hop.
