Facebook changes everyone’s listed emails to @facebook.com
While users can opt out of having their @facebook.com address listed, the troubling part of the change is how Facebook went about implementing it. The social network didn’t as much as announce the change was coming or alert users once it happened.
Interesting things start to happen once you realize that many people have Facebook contact sync, meaning that the email addresses for all Facebook contacts in their phone’s contact list will be replaced with the one from @facebook.com.
