shouldn't this keep javascript from facebook domains from loading?

  Yes, but a lot of data transfer happens on the backend without the client being involved.

    This is certainly possible but hasn't been my experience. Most of Facebook stuff is xhr that is easy to block on the client side. It's certainly possible that services are doing this on the backend, but it seems far easier to plug in Facebook's libraries in the frontend.
