Why any sane, rational person continues to have anything to do with Facebook is beyond me.
I have a very personal reason to despise Facebook and all its works. A few years ago, my wife got suckered into 'interacting' with a guy on FB, which cost us a stupid amount of money and very nearly our marriage. Where did the fault lie - with me, him, her or FB? I don't know, but I do know that without FB and its insidious way of invading your life, your privacy, your home, it wouldn't have happened. She still uses it, but I won't have anything to do with it and am deeply suspicious of any interaction with it. She'll still happily spend all day on it, and then tell me about this group or that person and how she feels angry or attacked or pissed off by this or that, how many or few likes this or that gets and I'm supposed to be think it important or feign interest? It brings no joy but only anger, frustration, distrust and nastiness into our lives. Do I have the right to forbid another adult from using something or imposing my will or opinions on that person? Of course not. So I suppose I must tolerate it, but it really bites.
A toilet is a useful device that takes human excrement and removes it from your life. Facebook is a Teliot - a device that finds human excrement pipes it back directly into your home.
I can see two options - do not have anything to do with FB or any product or service that does, or use it, but in a totally random way, so that the data generated is meaningless and of no value. It would take a large proportion of users to do this to make this strategy pay off, but imagine if the purchasers of FB data discovered that it was worthless... we can dream, but in the meantime, the only sensible course of action is to delete it from your life. As far as FB is concerned you are data, and data is their product. Stop supplying them with what they need. Do something - anything - else, but don't do Facebook. No good will come of it.
