I'm glad you raised this. To me, this case is most interesting not as a way to bash FB (I'm not a member), but as a conceptual marker: Is it OK for a user age

I'm glad you raised this. To me, this case is most interesting not as a way to bash FB (I'm not a member), but as a conceptual marker: Is it OK for a user agent, running on my hardware, to alter the way content is displayed? Can the FB TOS actually be binding when it restricts your ability to do this?
