For the right price I'm okay. I paid Netflix for an account but they use my data to train their algorithm and enhance their product. I don't know all the details behind their work. Am I not trading their privacy? Do I really know if they aren't selling my data my preference with another partner? Do I want to pay $$ for social network? I have to weigh what justifies cost for me; most of my friends won't pay for an account for Facebook, and because I enjoy having an online social network with my real life friends, I am okay for as long as Facebook doesn't sell my name to advertiser (they can track my browser history for sure and I know they do). I accept the risk and I keep a close eyes on my online activity so nothing backfires on me.
