The whole point is being forced to do it or not. I do not use Facebook, any Google service or anything that could track me, because I care. There's no control here, I'm not being forced to use those services and even if I were to use them - like most people who do not care for their privacy - it's just information being voluntarily shared. It makes no difference for them, and they can stop using those services/use an alternative any time they want.
