Facebook keeps framing thier role in providing OAUTH as one where they are protecting their users from all the bad guys on the outside. I thought it was clever marketing when I first saw them take this position but it seemed obvious to me that anybody who implemented Facebook login was giving Facebook the upper hand. One party gets free advertising and the other gets a scary looking permissions page that makes them look like an identity thief. In the process, the first party transmutes their bad press into the appreance of good will in countering the second party's apparent bad intentions.

Everybody must have caught on to Facebook's bad will psych game by now so why would anyone keep using Facebook Login?This latest change just moves the bad will to your login page. Every time someone moves to log in they will be reminded who Facebook thinks should be trusted and it's never going to be you.
