> I still have not agreed to the terms of use since I continue to be able to opt out and am amused by FB basically chickening out requiring their users to actually agree. The normal course of action would be to eventually block access to the app. That hasn't happened.

Me too. Every couple of weeks they show me a popup asking me to accept the new terms and I just click the x and continue about my day. At first they were threatening me that I'd lose access to the app by some date but that date passed months ago and I still have access. I'm amused because I feel like I called their bluff and it turns out they're not as confident as they make themselves out to be. One day they'll probably block me but until then...shrug.
