The saying "If you're not paying for it, you're the product" has some strange implications that I don't think people have completely thought through.
Did Facebook produce you? Did they produce me? No, I'm pretty sure our respective parents are responsible for that. Likewise, I'm pretty sure we aren't owned, and so that ownership can't change hands as a result of Facebook's business dealings.
It might be more accurate to think of us as resources that Facebook harvests. Like an orange juice company harvests oranges from orange trees, Facebook harvests our data.
