Since this change, I haven't seen any difference in my contacts. It looks like it's still pulling all available email addresses, not just facebook.com ones.
http://www.apple.com/ios/ios6/#facebook
(Click the "Contacts and calendars", and see that contacts can have multiple addresses, even with Facebook sync.)
Do you care at all if it something Androidish? Something from MS? From anyone except Apple? If no, then shut your hypocritical mouth.
