When my brother died in 2010, I posted to that effect on Facebook. Many friends (majority of them "real life," pre-Facebook/outside of Facebook friends) gave their condolences. Others called me. A few messaged me, etc. You get the picture. That correspondence was, and remains, important to me. Does Facebook own it? Can they delete it if they want to? Can they block me from accessing it? The answer, at least as far as…
Imagine how much better the world would be if a majority of people took the time to think about these issues as you have AND were also willing to simply boycott facebook until the ToS were changed. This level of personal responsibility would be much better, IMO, than falling back on the government to coerce facebook into better behavior.
Unfortunately it is not. Issues like this are the reason why government and state occasionally can be useful.
