Apologies for the misspelling, Sqad
My point is though, as you've said on several occasions that you don't use facebook then the only difference this is going to make to you on AB is you will see a blue connect to facebook button on the login page that won't work for you.
Hardly seems a big deal to me, anyone that doesn't use facebook can continue to use AB in exactly the same way and nothing will change, anyone that does use facebook will have to option (note, option, not forced to!) to authenticate their logigng onto AB by using there facebook credentials.
