Some points that are getting lost in the discussion below. I work at Facebook.<p>1. Facebook lets you export your data. It has been possible to do so ever since the graph API debuted in April '10. Since the market wasn't filling the gap, we even built a "download your information" product (<a href="https://register.facebook.com/editaccount.php" rel="nofollow">https://register.facebook.com/editaccount.php</a> -> Download Your Information). It gives you a zip file with all your contact info, photos, video, status updates, wall posts, etc. If somebody would like to write an importer for Diaspora, or Google Me, or even a non-vaporware competitor, they are well within Facebook's ToS, imho.<p>2. Facebook allows other sites programmatic access to the social graph. Yes, the supposed "crown jewels." That's exactly what Facebook Connect is for. You can see it in the wild on Pandora, Netflix, Yelp, Quora, and literally millions of other websites that are already doing what Google claims it wants to do: identify your Facebook friends.<p>3. Most importantly, what Google is insisting on is completely insane.<p>The ability to <i>export my friends' email</i> sounds good, but as with so many social product ideas (e.g., themed backgrounds for profiles), it stops sounding so good when you realize everybody has the same power. Think of it instead as: all of your Facebook friends can export your email to anybody who writes a Facebook app. Those spam quizzes? Every farm simulation knock-off flash game? The day Facebook does this, every Facebook user will wake up with their inbox crammed solid with spam from random Facebook applications that they do not even use.<p>What Google has not explained is why they need <i>friends' email addresses</i>, per se. Why couldn't whatever message they want to transmit be transmitted via Facebook messages, or wall posts, which send email notifications to almost all users anyway, and are already available via third-party APIs? This entire "not open enough!" straw man is a set of moving goalposts that Google will use to justify whatever competitive maneuvering they find convenient.<p><i>Facebook is in the right here,</i> people. The product decision Google is asking Facebook to take would be a disaster for Facebook users. Meanwhile, the lever Google is using to attack Facebook comes entirely at the expense of GMail's users, who before this episode were voting with their feet by the millions to import their contact data to Facebook, and no longer have that option. Google is making its users' lives worse, in an attempt to make Facebook make <i>its</i> users lives worse.
