I know what you're trying to get at, but I really don't think any person works this way. It's not just about Facebook. If parents or relatives own everything I write in online form, I cannot write anything online if I don't want them to read it in case I die. I can also not write it down in a diary since they will own that too. So really the only way I can safely share my secrets is in speech to friends. Some people cannot meet with friends, I myself have friends I have never seen in real life. So should I just not talk about my secrets at all then? Possibly making my life worse because of it.
