Also my thought: Are FB going to "unbork" all the displayed email values that they automatically and without user opt-in switched over to instead display these @facebook email addresses?
To me, it seemed an obvious ploy to keep user and their friends further captured within FB. Want to contact a friend out-of-band? Well, now (i.e. then) even though that friend chose to make their email address visible to you, you effectively no longer have it; you instead have this FB email address that forces you to remain within FB for this communication and until you manually request and receive that friend's "real" email address.
Now, supposedly emails to that FB address will silently forward to the person's "real" (registered) email address. You still don't, in these cases, actually have that address; everything still passes through FB, and you are dependent upon FB doing the right thing (or not) both morally and technically in forwarding your email on.
I'm not saying they won't. But the whole endeavour has become a mess that apparently stemmed out of the business' self-interest -- as opposed to the user's interest -- in keeping users "trapped" within its domain.
P.S. And would they do so correctly, reverting displayed addresses where the prior address values had been displayed to others, but not doing so where they had not been or had been displayed to a different set/group that current -- some people may have been comfortable displaying an @facebook.com email address once those became available but not their "real", personal email address.
2 days ago I was asked to respond to a survey on facebook and my opinions on the site. This ploy was one of my many gripes - I look forward to seeing the rest of my complaints actioned...
