We (the computing community) did this to ourselves. We created a situation where a HTML attachment received in email could plausibly look, to ordinary people, like something that would appear from trying to look at an ordinary PDF.

We have no one else to blame when ordinary people fill in their password and hit ‘Sign in’.
