Facebook doesn't have, and won't ever add, an 'export my photo albums, messages and friends list as a series of easily parsable xml files' button, because that would be building redundancy into the product. One of the ways that it locks you in is to to secure all this data, all this work that you've done. The fact that your friends all use it is obviously another significant factor. Similarly, I CBA to switch from Spotify, because I've got all of my playlists saved in it. If I moved to google play or one of the other up and coming music services, I'd have to rebuild these manually. There are some scraping tools to get this data out but they tend to be painful - "Just right click on each song and click 'copy HTML link'" etc ...
