Facebook recently updated its Terms Of Service to effectively say - "we own your data in perpetuity, even if you go ahead and leave Facebook. Complain all you like."
(Ok, I took some liberties with my summary). Anyway, Shades of Beacon!, they got slammed in the blogosphere, and had to bow down to the public's wishes. Here's what I saw on my Facebook home page yesterday:
What does this mean for Facebook? Without oversimplifying, they do need some of the updates in their Terms of Service, to better manage their network. And they would like to add some of the other updates, to be able to use data on their network better - specially for monitoring and monetizing.
My guess is that they'll slowly start adding a tweak here, a sentence there, and gradually update their Terms of Service to include most of the changes they wanted. It will just take them some time now.
