You are right in that Facebook is not a backup, even if it was a paid service. But the old age doesn't apply. While we may be the product we are also the client

You are right in that Facebook is not a backup, even if it was a paid service. But the old age doesn't apply. While we may be the product we are also the client. Fb does have a certain responsibility. Especially when they are encouraging people to user the platform for just what she as using it for. Ignoring any legal ramifications, it is in fb's best interests to help her because they need people like her. If we assume that we are the product, fb needs to do a certain amount of work to keep the product happy, or it goes away. I'm not saying they have to bend over backwards to help everyone, but at some point the backlash could hurt them... Yeah it probably won't, but it is still good business sense to help your "product"
