If "data portability" were interpreted widely enough, it would mean that people using other social networks could have a "proxy" Facebook account which is automatically synched with their main (non-Facebook) account. Ideally, any posts that your Facebook account could see would be fetchable by your non-FB account, and anything you post on your non-FB account would be re-posted on FB for you. This way, as far as your friends are concerned, you are a normal Facebook user, but you would never actually browse the site (or use the app). That would allow competition in how the UI works, but also less ad revenue for Facebook (and more engineering work, which they would presumably claim is unfair).
