"You can choose to keep in touch with your circle of friends, get invites to their parties, and so forth; or you can choose to remain concealed from your violent ex-boyfriend. Pick one."
That's kind of a douchey thing to do to people, even if you're a private company.
I'm no FB fan but, here, FB is not "doing" anything to anyone. They offer a service, and a social one at that. If people choose to use it to keep in touch with their entire social circle, then why is FB responsible for ensuring that no one has a violent ex-boyfriend, nosy boss, etc.?
If using FB will endanger your health, then don't use it. That's the missing option in your choice set.
BTW, this is what happens when people outsource their relationships to a profiteering third-party. No one seems to question the wisdom of that "choice". Instead they want to force FB to be something it never was or claimed to be.
