Did you read the article you linked?

You have a very uncharitable interpretation of Sir Berners-Lee's comments. He's railing against walled gardens being poor stewards of user data and having nonexistent data portability (as well as telcos violating net neutrality.)

Relevant then and even more relevant now. I see nothing about him wanting Facebook to enforce publicly-published profile data.

I’m not trying to pick on the guy. My memory is that this simply isn’t what data portability meant in 2010; data portability was widely understood to mean that there should be a public API to access any resources the Facebook web app will serve me. (Note how the article ties this into calls for Facebook to open up the social graph API.)
